Hi everyone, new to rollitup.
Just had a quick question, hoping someone here knows the answer.
Just bought one of those EziTools EC meters and tested my water. The thing reads just "01" and has a little 100 up in the top left corner of the screen.
I see everybody giving EC readings to the decimal point. eg. 1.5 or 1.7.
I'm starting to think this ec meter is a piece of inaccurate junk as I tested our dirty tank water and the front pond and it still just read "01".
Its brand new out of the box and says it has been factory calibrated. I know for a fact that my reservoir couldn't possibly be as dirty as the outside pond water.
Any ideas?
