Handheld Resistivity and Conductivity Tester

CDH-93 resistivity and conductivity meter uses automatic frequency conversion and booster technology to keep the electrode constant the same in different solution strengths.
$301.85
The CDH-93 resistivity and conductivity meter uses advanced automatic frequency conversion and booster technology to keep the electrode constant the same in different solution strengths. It can meet measuring accuracy in the whole range of this electrode by using only the one-point calibration function. The result is the high performance and the lowest cost.
