HI 8633 and HI 8733 Multi-Range Conductivity Meters for Laboratory Use
The HI 8633 and HI 8733 have been designed specifically for use in the areas of production and quality control. It is often necessary to test samples with different concentrations ranging from deionized water to brine. The amperometric system would require constant recalibration and probe changes, thus making the measurement process very time consuming and unreliable. To solve this problem, the HI 8633 uses a 4-Ring potentiometric probe. The rugged probes made in PVC are ideal for indoor as well as outdoor measurements.
By using one point calibration, it is now possible to obtain accurate readings across a very wide range from 0.1 to 199900 µS/cm.
If the temperature of the solution fluctuates, the HI 8733 with a built-in temperature sensor and Automatic Temperature Compensation is the perfect instrument.
As an accessory, the HI 721313 is available. The kit includes a rugged carrying case with a beaker, a calibration screwdriver and standardizing solution at 12880 µS/cm.
