When using ppm / ec meter

When using ppm / ec meter. For instance if you want 1100 ppm do you use Celsius mode?
Maybe a dumb question. I know Fahrenheit is less if I’m. Correct

Celsius and Fahrenheit you choose whatever you are accustomed to.
Does not have anything to do with getting ppm reading.
Hope I am not wrong😳


Celcius and Fahrenheit only has something to do with temp so what ot sounds like ur ppm meter has a water temp gauge built in thats all that means .so when u measure ur ppm it will tell you ur water temperature and ppm


@Indicabomb Sorry I am a few years out of the lab. For accurate pH and EC measurements our probes had temperature compensation. With water at ambient temperatures a grower does not have to worry.
