Water Quality Tester, Accurate and Reliable, TDS Meter, EC Meter & Temperature Meter 3 in 1, 0-9990ppm, Ideal Water Test Meter for Drinking Water, Aquariums, etc.

This water quality tester is an absolute must-have for anyone who wants peace of mind about their drinking water. It’s super easy to use, gives quick and accurate readings, and comes in a handy case. I tested it on tap, filtered, and bottled water and was impressed by the consistency of results. Highly recommend for homeowners or frequent travelers!

Very good tool to have handyEasy to use and after checking quality of drinking water I get comfort knowing that water that I drink or cook with is cleanHighly recommend and price is affordable

No, the battery does not last the “whole lifetime” of the meter. You do not specify “how long” does the meter last before the entire device must be replaced. So, does the ENTIRE DEVICE have to be replaced when the battery runs out?!I purchased this device back in 2018. It has been working just fine. However, just today I powered it on and the LCD screen did not display anything. I pulled out the circuit board thinking I just needed to replace the coin cell battery (CR 2032). To my surprise, the battery was wrapped around with some yellow plastic and fused to the device contact terminals. It was not meant to be removed, which is a silly design. I had to use a small plier and small flat headed screw driver to slowly remove the batter from the two terminals. The yellow plastic housing around the battery you no longer need so just dispose of the battery and that garbage yellow “wrapping”. Replaced the battery in the same location the original was found. Used small electrical tape to secure the battery and terminals. Slide it back into the plastic case and powered it back on. The LCD is now brighter than ever and testing different water sources works (try tap water, then bottled water, etc). Now in the future I can replace the battery and just use electrical tape to keep it secured again.The LCD color is nice as it shows RED when water PPM hits above 40 (my case it showed 320!). Bottled water from two separate sources showed 15 ppm and 7 ppm.It’s a tiny lightweight device that easily fits into your pocket or backpack if traveling. The clinic cell battery should last for years but for the company to purposely FUSE the battery to the terminals is annoying. However, looking at the latest photos of this product today, it seems like they changed the battery compartment design. Now you may be able to easily remove the battery for replacement.Taking away one star only because of past flawed design, but it may have been redesigned today. Either way, I was able to DIY to resolve the battery replacement issue for my 2018 model. Other than that, I do recommend this device.

Very interesting and useful device. It’s easy to carry, to understand, and it’s accurate.A great “good health resource.

The tester works great, It's pretty consistent with its readings. and to tell you the truth it's fun testing different water sources, tap, bottled, and distilled water. I plan to take it with me where ever I go where I will drink the water.

GreatI now know the correct water to drink. Easy to use.

This TDS meter worked perfectly right out of the box. I immediately tested our tap water hardness and temperature. It told me just what I expected. Our water is awful! Now to start looking for whole house filtration. I do have a filter under the kitchen sink, and tested the cold water there. It read about 150ppm less than the hot water side, but still unacceptabley high. This is a nice tool to have around.

It test water quality but it is confusing, in terms of functionality bc it has a red or green backlight but i dont think that has anything to do with water quality rather TDS. I can not 100 percent confirm the accuracy bc I doont know much about TDS and only have 1 tester. its build its decent but the battery cap sometimes fall off. it did come with a cute carrying case. it reads almost instantly so there is no wait time for results and overall not bad of value for money.
