Useful test only took a couple minutes, water tester showed exceptable levels. Did show visible signs of calcium deposits but the device did not detect any harmful contaminants., 5 Stars!

The ATuMan TDS Meter has been an interesting tool in my household for ensuring water quality. Its compact design makes it easy to use, and I appreciate how quickly it provides readings. I have an intense, in-line, 3-stage water filtration system under my kitchen sink that removes chemicals and heavy metals as well as alkalizes and structures the water. I've use this for testing that water and my straight tap water in the bathroom, and it has consistently delivered accurate results. The clarity of the display and the user-friendly interface make it straightforward to operate, even for someone new to water testing. Knowing the turbidity and temperature levels has given me greater confidence in the water I use for various purposes. Despite the simplicity, ease of use, and reasonable price, this meter has truly enhanced my understanding and management of water quality in my home.

I like that the ATuMan TDS water tester is a nice compact size (comparable to a highlighter pen) and easy to use.There is only one button to use:- 1st touch: Turns on & reads TDS in ppm- 2nd touch: Reads water temperature in degrees CelsiusWhat I don't like it that the display readout is small.Additionally, because the display is slightly curved, is reflects glare from the ambient light.Both of these factors make the display somewhat hard to read.

I’m always curious if the water I’m drinking is clean. All water tastes so different. And it grosses me out. So I got this to test water. The results are shocking!! I’m so glad this device works! All you have to do is put it in a glass of water and read the numbers!

I wanted to test what my city water vs. my bottled water was like and I also included filtered city water.The meter was very easy to use. The Measurement is instant and it's easy to read the display.Great little meter that does what it's supposed to do.,

I've used this TDS meter to test RO water from a newly installed filter. It reads the TDS quickly and has been giving me consistent readings. I don't own a more expensive tester, so I can't say just how precise it is, but this had been reading between 1 and 2 PPM with RO water and around 40 for my city's tap water.

I've always owned black cars. Pain to take care of, but looks fantastic when clean. Mr Clean used to make a clunky soap and rinse device that connects to the end of a garden hose. Use it to spray soapy water onto the car, wash, then turn a dial and rinse using water than ran through a deionizing resin bed that took out the minerals. That product has long been discontinued, but now they sell dedicated resin systems. But how do you know when the resin is depleted? This pen.I tested on water from my tap (66) and distilled water (0). Convention is anything over 50 will leave spots. I have a small resin system for car washing as well as PV panel cleaning. Having a meter like this means I don't have to guess when I have to change out the resin.
