iv got 2 hand held tdsmeters that give 2 different readings.
they both read 000 on my water out the pole but the water out the tap is about 20 to 30 ppms out from each other?
any help on how to sort this??

cheers joe

by the way they are to different makes dose that matter?

get some Calibration solution to re-calibrate your meters to double check!
