Hello all,
So I have a Guardian Monitor by blue lab.
I am new so bare with me here.
The EC readings there are 3 and are as follows;
EC
TDS (EC x 500)
ppm (EC x 700)
I am unsure if I should be using TDS or ppm for most accurate readings.
Please do let me know.
From what I have read EC x 500 is for US and x 700 is for EU correct?
