great working product

This meter works great to know the quality of water

I really like how easy and how fast this meter works

This inexpensive TDS tester works quite reliably to my surprise

The water at work tastes terrible and I used to check its quality.
-
This worked fine the first time I used it

The top lid is constantly falling off exposing the wires and board inside which isn’t too great when working around water

works, easy to use, fast shipping

They are both great they are both great work perfect

Our new expensive R/O unit filters need changing when the TDS is greater than 25.
