Hi guys I would like to know if I have to make some kind of calculation after I check ith the TDs meter…so the numbers on my tap water is 156 ppm and 352 μs/cm
And I guess the μs/cm it’s the EC
No calculations for ppm. Your meter reads in micro Siemens for EC so you just need to move the decimal 3 places to the left for EC. So you have an EC of .35.
