ONLINE Portable electrical/conductivity meters with ISO CERTIFICATE

Descriptin:

The conductivity meter is a digital display microcomputer online controller can be equipped with a conductivity electrode with temperature compensation. Conductivity is the ability to conduct current object. The conductivity meter measuring principle is two parallel plates, placed in the test solution, the ends of the plate with a certain electric potential (typically sinusoidal voltage) and then measuring the current flow between the plates .
