Poit Water Quality Digital TDS PPM Meter Tester, ATC/Measuring Temperature/Data Hold/Auto-off Function, Leather Carrying Case Included

This meter was a good Prime deal and readings seem to be consistent. The only things that would have made me happier would have been a slightly larger display and a lighted display. Those two things aside this is a nice meter...

I purchased this after getting a water purification system and it showed the exact numbers as the meter from the the guy who did the installation. It's also fun to show friends and family how their bottled water from the grocery store is a waste of money, because it's not pure.

Tap water - 55 ppmDistilled water - 0 ppmFiltered water - 25 ppmNo the most professional and durable feeling device

What can i say, I dip it in water and i get a reading. not sure what i means but i can compare between my RO's water, tap water, bottled water and distilled water. Gives me an idea on water TDS.

Easy to use, gives few details but worth the money!

Efficient meter

Works fine

Works great. I use it for making colloidal silver. Good value.
