Hi guys,
Just got a prozor TDS and EC test meter
From Amazon only 10 pound. Just tested my water straight from the tap and it's reading 155 TDS. Do I have to buy a solution for this pen to dip into every so often if so how often do I do this. What kind of solution is it as nothing is said in the manual.
Thanks lee
