We use these to test/verify the TDS in our incoming water as well as in our treated water in order to keep our patients safe. They keep their calibrations well, and work day in and day out. We put them trough rigorous use and they prove to be durable. Hard to find a con here.

When consistent quality counts
April 20, 2014
Verity Water from Upstate NY
I have used the Myron L TDS meters for over 13 years. I can always count on reliable results in the ranges I need for the water treatment industry. The Myron L meters stay calibrated for very long time frames, but when calibration is needed its a snap.
