Magnetic Stirrers Timer Controlled

Timed stirring for efficiency


HI 322N and HI 324N incorporate a timer control that will turn the motor off after the selected amount of time. The time is adjustable from 5 minutes to 2 hours. This feature allows the user to carry out other tasks without worrying about over or under stirring. These units are heavy-duty stirrers. HI 322N and HI 324N can stir up to 5.0 liters (1.3 gallons), making them ideal for laboratory and production use. These stirrers allow regulated speed control. A limiter will assure the maximum speed is never exceeded (Speed safe'”), and a VCO device stops motor acceleration as soon as a load is removed. HI 322N and HI 324N have an automatic feedback feature with HI 324N also incorporating an LCD tachometer. The motor is electronically controlled to maintain the chosen speed as the load changes. If the viscosity or the level increases or decreases, the circuitry will adjust the output power. The RPM display guarantees repeatability in QC tests and research by constantly displaying the RPMs.

Magnetic Stirrers Auto-Reverse With Tachometer

Stir in 2 directions with RPM on display

When stirring a solution, to work with a constant speed (Revolutions Per Minute) is an important factor in ensuring that the best repeatability in tests and processes is achieved. Without a tachometer, there is no way of knowing the RPMs. HI 304N is a heavy-duty stirrer with a built-in tachometer. It is often desirable to stir in two directions in order to achieve maximum homogeneity. An advanced circuit allows HI 304N to reverse the direction of the stir at a user selected interval. The interval can be adjusted from 30 seconds up to 3 minutes. In addition to precision speed control, a limiter will also assure that the maximum speed will never be exceeded (Speedsafem). Often, a sample is removed from the stirrer before the uses reduces the speed with ordinary stirrers. This can cause the motor to accelerate until it is destroyed. HRNNK stirrers incorporate a VCO device that will stop the motor from accelerating as soon as the load is removed.

Magnetic Stirrers Two-Speed With Tachometer

Exact RPM on LCD display

QC stations and labs must be able to repeat tests and processes. In order to do this, this specifications must be clear at all times. When stirring a solution, the RPMs are a very crucial factor. Without a tachometer, there is no way of knowing the exact RPMs and therefore no way of repeating the process. The HI 301N solves this problem by incorporating and LCD tachometer. These stirrers also allow precise stirring repeatability by using two separate ranges. In each range, the speed can be fine tuned for exacting accuracy. This assures maximum repeatability in experiments and processing for laboratory as well as production use.

In addition to speed control, a limiter will assure that the maximum speed will never be exceeded (SpeedSafe"‘). HANNA stirrers incorporate VCO device that will stop the motor from accelerating as soon as the load is removed.

Stir Samples in 2 Directions


HI 312N is a powerful stirrer that stirs up to 5.0 liters (1.3 gallons). The HI 302N model can stir up to 2.5 liters (0.66 gallons). It is often desirable to stir your samples in two directions. This will achieve maximum homogeneity and solubility. An advanced circuit allows HI 302N and HI 312N to reverse the direction of the stirring at a user selected interval. The interval can be adjusted from 30 seconds up to 3 minutes.

In addition to precision speed control, a limiter will also assure that the maximum speed will never be exceeded.

During repeated testing, samples are often removed from the stirrer before the speed is reduced. This could cause the motor to accelerate until it destroys itself. HkNNl\ stirrers incorporate a VCO device that stops the motor from accelerating as soon as the load is removed (SpeedSafe"‘). In addition to this feature, HI 312N also has an automatic feedback feature. The motor is electronically controlled to maintain the chosen speed as the load changes. If the viscosity or the level (fluid weight) increases or decreases, the circuitry will adjust the output power.

Magnetic Mini-Stirrers

Compact and lightweight stirrers

Common stirrers are manufactured with steel and aluminum components. These units are often too large and heavy to git in the limited space of a laboratory. The hi 190m, hi 190mb and hi 200m are
compact and lightweight, so that lack of laboratory bench space is no longer a concern.


These stirrers incorporate electronic controls that allow the user to regulate the speed with greater precision. Often, in the lab, a sample is removed from the stirrer before reducing the speed. This would cause the motor of conventional equipment to accelerate until it is destroyed. This does not pose a problem with hanna mini—stirrers. In fact, the internal speedsafe” mechanism will ensure that the maximum speed is never exceeded.


hi 190m and hi 190m-o come supplied with an abs cover that will resist the harmful effects of chemicals that are accidentally spilled. The abs-covered mini-stirrer is available in two versions: hi 190m operating at 110 or 220 vac and hi 190m-0 at 12 vdc. This provides you with the flexibility to choose between field and lab models, as well as being able to use the hi 190m-0 for applications where a low input voltage is a must.

Magnetic Stirrers

Magnetic Stirrers

There are two types of magnetic stirrers; mechanical and electronic. Most manufacturers of magnetic stirrers use the mechanical approach. They use steel and aluminum for the structural material and outdated methods of speed control. These units are not only very heavy, but also very inaccurate. The use of these materials and methods appear to make the units rugged and strong. But, they are instead, cumbersome and outdated.


Something as simple as completely dissolving salts in a medium, is in reality, a science. Often this cannot be achieved with simple mechanical processes. The only choice that the user has with
mechanical products is to increase the stirring time or the temperature. With electronics, you can do more. . . The hanna approach is electronic.


Speed sensor and limiter: each hanna stirrer is equipped with a speed sensing device (opto-sensor) coupled with an fvc (frequency voltage converter), which monitors the speed. As the speed reaches a preset maximum level, the speed limiter shuts down the vco to slow down the motor speed. This ensures that when the load is suddenly removed from the stirrer, the motor will not accelerate to such a high speed that will be hazardous to both the user and the stirrer; a feature not commonly found in conventional stirrers.


Accuracy: adjusting the stirring speed with a mechanical stirrer is inaccurate. Similar to the "zoom" function of a ranges of speed by using electronics. This assures  maximum repeatability in experiments and processing. Auto-feedback: in addition, with the hanna auto-feedback stirrer, any change in viscosity or volume of the solution is automatically compensated for, to keep the speed constant.


Sophisticated engineering ingenius design, employing sophisticated electronic technology, offers the best performance. Parts are engineered and manufactured to strict specifications to ensure absolute reliability. All components are mounted into a molded casing covered with a stainless steel plate, which is splash proof and chemically resistant. Minimal vibration and a well balanced rotating arm provides years of trouble free operation that hanna’s users are familiar with.


Safety

An on/off switch and a fuse located at the rear panel provides easy access to shut off power, in the event of a short circuit. The circuitry is grounded to the case for additional protection.

Magnetic Stirrers ( HI 302N / HI 312N)

Stir samples in 2 directions

Hi 312n is a powerful stirrer that stirs up to 5. 0 liters (1. 3 gallons). The hi 302n model can stir up to 2. 5 liters (0. 66 gallons). It is often desirable to stir your samples in two directions. This will achieve maximum homogeneity and solubility. An advanced circuit allows hi 302n and hi 312n to reverse the direction of the stirring at a user selected inteval. The inteval can be adjusted from 30 seconds up to 3 minutes.


In addition to precision speed control, a limiter will also assure that the maximum speed will never be exceeded.

During repeated testing, samples are often removed from the stirrer before the speed is reduced. This could cause the motor to accelerate until it destroys itself. Hl ni\ stirrers incorporate a vco device that stops the motor from accelerating as soon as the load is removed (speedsafem). In addition to this feature, hi 312n also has an automatic feedback feature. The motor is electronically controlled to maintain the chosen speed as the load changes. If the viscosity or the level (fluid weight) increases or decreases, the circuitry will adjust the output power.

Magnetic Stirrers ( HI 303N)

Exact RPM on LCD Display

QC stations and labs must be able to repeat tests and processes. In order to do this, this specifications must be clear at all times. When stirring a solution, the RPMs are a very crucial factor. Without a tachometer, there is no way of knowing the exact RPMs and therefore no way of repeating the process. The HI 301N solves this problem by incorporating and LCD tachometer. These stirrers also allow precise stirring repeatability by using two separate ranges. In each range, the speed can be fine tuned for exacting accuracy. This assures maximum repeatability in experiments and processing for laboratory as well as production use.

In addition to speed control, a limiter will assure that the maximum speed will never be exceeded (Speedsafem). HkNNF\ stirrers incorporate VCO device that will stop the motor from accelerating as soon as the load is removed.

Magnetic Stirrrers (HI 304N)

Stir in 2 directions with rpm on display

When stirring a solution, to work with a constant speed (revolutions per minute) is an important factor in ensuring that the best repeatability in tests and processes is achieved. Without a tachometer, there is no way of knowing the rpms. Hi 304n is a heavy—duty stirrer with a built-in tachometer. It is often desirable to stir in two directions in order to achieve maximum homogeneity. An advanced circuit allows hi 304n to reverse the direction of the stir at a user selected interval. The interval can be adjusted from 30 seconds up to 3 minutes. In addition to precision speed control, a limiter will also assure that the maximum speed will never be exceeded (speedsafem). Often, a sample is removed from the stirrer before the uses reduces the speed with ordinary stirrers. This can cause the motor to accelerate until it is destroyed. Hf ni\ stirrers incorporate a vco device that will stop the motor from accelerating as soon as the load is removed.

Automatic Titration Systems (HI 901 / HI 902)

Powerful customization, accurate analysis

Hi 901 and hi 902 are automatic titrators from hf nk that compliment our wide range of products dedicated to quick and accurate laboratory analysis. Hi 902 also features the addition of back-titration
capabilities.

Each unit is provided with a host of numerous features suitable for routine sample analysis. Hi 901 and hi 902 perform acid/base, potentiometric and amperometric titrations.



These versatile titrators support up to 10,000 methods: standard or user defined. When powered on, the instrument initiates an internal diagnostics check and then readies itself for the first titration of the day. A large lcd screen clearly shows the chosen method, correlated information and also indicates which parameters may be adjusted. A real-time titration curve is shown on the display; this feature is useful when new methods are tested or when a procedure needs to be optimized. At the end of the titration, all data, including the graph, are automatically stored in memory and can be copied to disk via the built-in floppy drive or through direct connection with the serial cable supplied with the titrator. The titrators are equipped with an rs485 serial port.

Burette maintenance is simple and completely automated. The user can decide to purge it or wash it and can select how many washings to perform.

With our exclusive clip lock” system for burette replacement, changing from one titrant to another is done in a flash! Often, preliminary titration operations are very long and arduous. A burette often needs to be adjusted for correct dosing, which extends waiting time for new sample analysis. Hknni\ has engineered a way to solve this problem. The innovative clip lock"‘ system allows users to change burettes in two simple steps, passing from one titrant to the next without any problem. Additionally, hi 901 and h1902 automatically recognizes the volume of the new burette.  
 
Both hi 901 and hi 902 can drive two pumps, with the hi 902 incorporating a more advanced system. While the hi 901 can drive the two pumps separately, hi 902 can also drive them concurrently
and perform back titrations. Hi 902 can perform more complex functions with the ability to determine more than one equivalence point.  
 
Users can connect ph or 0rp electrodes to this unit, as well as create a complete workstation with a pc, monitor, keyboard and printer. This unit complies with glp specifications, providing validation support for analysis. All glp information from each sample can be stored, including id number, date and time of analysis, electrode id code and last calibration date.
