zub0 249 Posted November 16, 2013 Share Posted November 16, 2013 there is no difference in ppm and ec meter in how it measures they both measure ec,the pm meter then convert it to ppm using manufactures conversion making it unreliable as 2 different ppm will show different values measuring same water making it inaccurate. i covert using approx value of 1k ppm=1ec worked so far. hope this bit helps u on ur quest have a nice day Quote Link to comment Share on other sites More sharing options...

zub0 249 Posted November 17, 2013 Share Posted November 17, 2013 i tried tokage converter and seems my ppm meter has been very inacurate as site says 1k ppm is 1.5 ec. u could just messure same water with ur and ur friends meter and u will see how it's values compares Quote Link to comment Share on other sites More sharing options...
