TDS Meter, Electronic Water Tester with 0-9990 PPM Measurement Range, Hand Held Digital Water Test Pen for Farming, Aquariums, Pools, Household Drinking Water (Blue)

Works great. Tested many types of water from different resources and was shocked to see the variations through out.

I have an expensive water system in my house and I was shown how to test for safe drinking water. I purchased this monitor as recommended and it works as well as my water companies. I have actually shown several of my friends how bad their drinking water is which they did not believe until they saw my results and they have a cheap filtering system. Most tap water here in the US is actually not safe to drink unless you have a really high grade filtering system which is worth every Penney .

It works! We have tested our own running water from the facet and the zero water we make and it shows the difference.

This PPM meter works great….it’s limited to 999ppm so anything over 999ppm will need another meter….also it’s not backlit which is a common feature…..I’m not sure if it turns itself off when not in use because I gave it away

Bueno

Cumple lo que promete, muy buen producto

works great price is right

It's really easy to use this device, and it wasn't expensive.It helps me get a better understanding of the water's cleanliness. I wish they made some that could detect plastic, but I realize that sort of goes against how these particular devices work with electricity and what not.
