I have a hand held TDS Meter that i use to check my water, I also have a new inline tds meter on my system too, both give different readings and i think the handheld meter needs calibrating with NaCL, how do you do this ? or is it as easy to buy a new meter ? cheers

could i just put new resin in my DI unit to make sure the water is ooo tds pure then calibrate with that?
cheers
