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.

I purchased this product to replace one that I had bought a long time ago and the battery was going bad and not replaceable. The old one worked okay. This one works better than okay, it's quick, easy to read and I feel that is accurate. I'd like to how safe the water is that I'm drinking. I recommend this product.good build quality,gives instant reading

I live in a country with serious issues when it comes to water quality. I have a friend who works in a major Lab that does quality control for food and water and the results i got from this tester were 90% close to what my friends lab has register for every water brand available in our market. Including tap water. What a life saver because specialized "baby water" costs almost 3 times as much as regular water... turns out the share the same quality and amount of minerals!

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.

I’ve now used it in Tokyo and Korea. According to this test, hotel water is fine, which was actually a surprise. But at numerous restaurants in both countries…. It was horrible water. Not sure of what it’s actually testing, or what contaminants are in the water. But it has been a real eye opener. Especially the hotel water, which I’ve never even thought to drink. But now realize it’s fine in a pinch.

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.

Absolutely. I conducted a test of my tap water at my home and I had a bottle of water and I was just amazed at the difference and the level Of which it was showing how contaminated and harmful our tape water is that we've been drinking each and everyday.

This has proven that my tap water is bad 201ppm. Also, the Nokii water container that I bought on Amazon just brings it down to 176ppm while the bottled water was 20ppm. I will be traveling to other locations and friends homes to loudly announce to all the other guests if the host is trying to poison us all. Easy to use.

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.
