Reliable and Waterproof

Multi-range Conductivity Meters

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, HANNA

instruments has developed the HI8633, which uses a 4-ring potentiometric probe. The rugged probe

is made of PVC – ideal for indoor, as well as outdoor measurements.

It the temperature of the solution fluctuates, HI 8733, with a built-in temperature sensor and

Automatic Temperature Compensation, is the perfect instrument.
