TDS Meter Drinking Water Tester Digital Water Quality Tester for Filtered Water Tap Water PPM EC Meter with ATC for Water RO Systems Hydroponics Setup Hot Tub TDS Range 0-8600ppm

I LOVE this product. It’s so accurate. I thought I would only be able to use it once, but I was wrong. You can use it forever! I took it to work and my coworkers got to test their water of choice and find out how drinkable (or not) they were. And it’s so affordable! Definitely worth it!

easy use, like it!

Purchased on 09-18-2023 for $11.58. ($12.85 - $1.29/10% Discount)It turns on. It takes a reading. It displays the result. That's about all that I can state with certainty.Is it accurate? I have no idea!The problem is that if you have no reliable benchmark of the water that you're testing, you don't know if the measurement given by this tester is accurate. You have to take it on faith that it was calibrated correctly and accurately at the factory.If your neighbor is an engineer with the local water district and has a $25,000 water tester that gets calibrated everyday, you know that it's accurate. So, when he measures your tap water and gets a reading of 200 PPM, you know that that's accurate. And that gives you a reliable reference number as a starting point to gauge the accuracy of this tester.But, I don't have a neighbor who is an engineer with the local water district who has a $25,000 water tester that gets calibrated everyday. What now?Who polices the police? Who tests the testers? There's no 'Good Housekeeping Seal of Approval' equivalent, so...There's a way to calibrate this at home, but they tell you to use a special solution---WHICH THEY DON'T INCLUDE. So how?Well, I have to take it on faith and trust that the tester is accurate. I have no choice but to believe that it's reliable. Not a great place to be.It was inexpensive, so that's good. I guess it's better than nothing.Not exactly a rousing endorsement...If that engineer who has a $25,000 water tester moves in next door, I'll update how accurate this is.

I love it. It works.

Really showed the true quality of water, tap and purchased water. This is worth it.

Very easy to use, clear instructions are included which you will need at first as the list of features is quite large. I've been testing water all over the place, the bathroom, the kitchen, the back yard even the ocean! (just to see what would happen) It can be a little worrying when you see the display creep towards red! Overall, very useful tool to keep in that random kitchen drawer.

Easy to see the numbers. Comes with directions. Appears to be accurate. I like it better then another one I have.

Easy to use , good price and seems pretty accurate. I definitely recommend it .
