HANNA Instruments Laboratory Division has released the HI8733 multi-range conductivity meter. It is designed for production and quality control, where samples of different concentration will be tested.
It measures conductivity in four ranges, 0μS/cm-199.9μS/cm, 0μS/cm-1999μS/cm,0.00mS/cm-19.99mS/cm and 0.0mS/cm-199.9mS/cm. The measurement range is selected through the front panel of the instrument.
All readings are temperature compensated and the temperature coefficient is adjustable from 0% to 2.5% per ºC. This is important with acidic, alkaline or highly saline samples.
The four-ring potentiometric probe is constructed in PVC for durability. The system requires manual calibration at one point. It is supplied with conductivity probe, calibration screwdriver, 9V battery and an instruction manual.
