Used these for years and they never fail. I have an in line TDS for in and out of my system but if I need to double check, I use a hand held and they always steer me right. Fast delivery as always ☺️
Great item and quick delivery, batteries last for ages, really handy little meter
Excellent product good to keep an eye on your water ppm
It works on normal water - yet to test on DI water
Very useful, multi-functional, and of good quality.
