Water Testing Kits for Drinking Water- 4 in 1 TDS Meter TDS EC & Temperature(°C,°F) Meter,Accurate & Reliable Digital Tap, Well, Swimming Pool,Hydroponics, Aquarium, RO/DI System

This water tester is a must living a region with hard water. Super quick and intuitive to use: I have been able to measure effectiveness of filter replacements or an RO upgrade.

Works like a charm

Checked my water at 3 different sources and came up with a reading +/- 3 ppm, so at least the results are consistent. Accuracy is unknown. Reading seems a little low (220pm), have super hard calcium/mag rich well municipal water stains everything. Gonna try with a bottle of distilled water.

I love this it was simpler than I thought it would be to use and utilize I like to thank you for this product

Every household should have this tool. Know what levels are in your taps. We test whatever we can. Makes a great gift! Love it.

I bought this to test my tap water and my filtered water. The tap and filtered water ended up being the same exact number so I'm honestly not sure if this things sucks or the filter was crappy. I ended up buying bottled water to test and those came up with different numbers so I'm thinking the filter was subpar. Not sure about accuracy, was fast reading though. If it is the filter and not this tester I would say it is worth the money as it was under $10.

To use this meter, you must understand two things. The temperature correction to the TDS reading matters a LOT. And this meter's temperature correction is EXTREMELY slow. The "30 seconds" in the instructions is not nearly long enough if your water and your meter differ in temperature by more than a degree or so. I'm using this to test my tap water. Straight out of the tap, it's about 10 degrees F colder than my kitchen. At first, I thought the meter was garbage, because the readings were all over the place. The longer the water sat around, the higher the TDS reading got. I eventually realized that's because the water was warming up. Now, I take a sample, let it warm to room temperature, and the meter is extremely consistent from reading to reading. Bottom line, if you think the readings from this meter aren't stable, then consider "operator error" as a possible cause. I feel that I got far more than my money's worth, for $6 or so. But for $6, you get a meter that's reasonably accurate, but very slow. This meter does, eventually, make a temperature correction to the reading. But, it does so extremely slowly.
