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​​

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!

Works great and is easy to use. Clear readings and fast results.

As a first time hydroponics grower, I’m still learning a lot. Such as, I learned to use RO water instead of my well water because of the extreme concentrations of dissolved salt in mine. I lost my first batch of strawberries to it before I even knew what happened. EC reading is actually my main purpose for this meter, although the PPM and temperatures are also needed information. This product is easy to use (once you figure it out) and seems durable. The directions were non-existent, so remember to hit “clear” for accuracy between taking readings at separate reservoirs. The temperature and PPM are standard readings, however, I dropped a star based on the fact that EC on this unit is NOT measured in the standard Millisiemens/centimeter. It’s actually Microsiemens/centimeter (divide the number on this unit by 1000 to get mS/cm). As a new grower, it baffled me how I could be getting a reading of over 400 mS/cm after correctly adding my plant food and fertilizer while my plants require 1.8-2.2. It would have been nice for the instructions to explain this on the unit. Standard drinking water should have a value of under 0.3 mS/cm (Which on their meter will actually read 300 mS/cm). At least now, you can now use this example as a reference while checking the EC for your water. Other than that, this unit seems great. I’ve only had it a month, so I cannot comment on the longevity. For the price, I’m not expecting it to last forever.

Dependable, reliable and accurate time after time. We live and travel in our 5th wheel full time so we're in a different park every one to three months and sometimes their in different states or different parts of the country that means different water supplies with different possible issues we have onboard water filters and inline filters but we still check the water at the source and in the rig when we arrive at a new park and at least every couple weeks while parked just to make sure our water filters are working properly and are protecting us. Clean water is a must for drinking, cooking and showering so changing the water supply often has the possibility of causing issues with our health checking the water quality couldn't be easier that what this great little tester is it's as simple as turning it on and placing it is a glass or cup and reading the information it provides we can use this anytime and anywhere we are and know immediately if the water were using is clean and safe. This tester is small enough to fit into any overnight bag, drawer or anywhere else you want to keep it it's fast, reliable and goes a very long time before needing new batteries and the first set of batteries are even included as well as a nice leather case to store the tester in. The tester can be used to test aquarium water , pool water or any other body or type of water I know we feel much better when we know as much as possible about the water we're using and giving our Grandkids when they travel with us having and using this portable water tester has given us a valuable tool and peace of mind and control of our water quality.

Works well. Have not tried the temp feature. Use to measure the TDS in my reverse osmosis system

Good quality water tester. I use it to test top water and filtered water which is accurate.

easy to use, appears to be accurate as compared to other TDS meters I tested

Hard to interpret results using color scale.

Muy buen instrumento de medición

Great product

Works very well for me. We like it.

Good and efficient
