GENERAL DESCRIPTION

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. Both models can be manually calibrated at 1 point. The HI 8733, with a built-in temperature sensor and Automatic Temperature Compensation, is the perfect instrument for measuring samples with fluctuating temperature. HI 8734 has been specially designed for the water conditioning industry, particularly in the softening, demineralization, reverse osmosis and drinking water applications. Three ranges of measurement assure the highest accuracy possible. In addition, Manual Temperature Compensation is possible through a knob on the front panel. The ratio between conductivity and TDS is factory set at 0.5. Moreover, the 4-ring potentiometric probes supplied with the meters are made of rugged PVC - ideal for indoor, as well as outdoor measurements.
