TDS Meter, Digital Water Tester - Accurate and Reliable, Measures TDS, EC & Temperature (°F/°C), 0-9990ppm, Water Test Meter for Drinking Water, RO/DI System, Aquariums, etc​​

The HoneForest TDS, EC, Temp Meter 3 in 1 works great. This device is powered by a CR2032 lithium battery. In TDS mode measures the Total Dissolved Solids in water being tested. The higher the reading the more inpure the water is. A reading of 0 ppm (parts per million) would be deionized water. A reading under 50 would be purfied water. 50 to 100 would be hard water. 100 to 400 would be typical tap water. Anything above 500 does not meet EPA standards. The EC or Electrical Conductivity deionized water is not very conducive while most city tap water is almost as conducive as copper wire. This device also measures temperature in celsius and Fahrenheit. Small size, very durabile, changed scales easy, light weight, and brightness makes for easy to read even in full sunlight or the darkest places.

I’m extremely happy with the HoneForest TDS Meter! I used it on my tap water (98), distilled water (0), and filtered water (88), and the readings came out pretty good! It was really interesting to see the clear difference between the three. The device is very easy to use right out of the box. Just turn it on, place it in the water, and within seconds you get a clear reading for TDS, EC, and temperature. It feels well-made for the price, compact, light weight, and reliable. If you want a simple and accurate way to test your water quality at home, this is definitely worth it. I highly recommend it!

had mine for several months now and it's still working ok. every so often it will flake out a little with really low readings but resetting it or clearing it a few times usually does the trick. for this price I would buy again.

I purchased this in 2021 after installing a whole house filtration system and a RO system in the kitchen. After having tested for base line, I use it to monitor periodically. The device is easy to use and has a guide on the unit that is easy to follow. I have compared the water from my RO system to bottled water, and the TDS meter allows me to see the effectiveness of both my RO system in the kitchen and all other water throughout my house. Very pleased with quality.

It is easy to operate and read.

In early february 2020, I got some weird bug. For a couple months afterwards, everything tasted like metal and plastic. Water all tasted like dirty fishtank (if I got it from a refill station) or plastic and chemicals (if I bought in a store). So, I bought this to see whether the water was all actually bad, or if it was just me. Turns out, everything tasting bad was one of the less common side effects of COVID. Tap water here is legitimately gross, but no one drinks that anyway. A couple years later I was able to buy a house and install an RO system, and this is still useful for testing how well the filters are working. It can be useful to have an actual number instead of just saying that the water tastes gross.

Its worked great so far. Seemed like a legit reading as it matches ppm expected with measurements. Has lasted for over two months and survived drops on the floor. Very good for the price.

I can't figure out how to have it perform per the instructtions. Specifically, I"'m talking about holding the temp and ppm. The other thing is that i use the clear function and it doesn't clear. I think the ppm and temp functions are working correctly in terms of them displaying an accurate number.

Works very well for me. We like it.

Does the job

Good and efficient

Very easy and accurate

Funciona muy bien con los TDS, en mi caso si marca los mismos que me marca mi llave de agua pura y filtrada, lo use para ver los tds y después escoger mi sistema de purificación y arrojo la actualización muy bien.
