Conductivity vs Mho

Date : 8/7/2018
From : Marty

Question

I am using the resilite R7031-20K sensor I have a red light indicating that my purity is greater than the sensor allows which I assume is 20K ohms 50 mho per the sensor literature I have When I test the water with my conductivity meter I am getting 119uS According to calculators 119uS is like 00019S which is equal to 00019mho which is well below the 50mho limit specific by the unit

Could my sensor be bad Or am I calculating or understanding something incorrectly

Thanks for any feedback


Answer

It isn't mho’s it is micromhos. 1 micromho = 1 microsiemen = 2 p.p.m.

This should help

At 119 mS that’s is close to 60 p.p.m. and would turn the light red.
