Review: Digital water tester - It works well and instantly.
Review: Excellent meter, very slow temperature correction. - 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.

### ⭐⭐⭐⭐ easy to use but could have included better instructions
*by J***S on September 3, 2024*

Using this is as simple as removing the protective cover and dunking the pronged end into water (no higher than the line). The LED screen give the reading. There are four modes, but no clear understanding in the short instructions provided explaining what each mode means. I understand the difference between celcius and farenheit but not the other numbers displayed. For this reason I gave it only 4 stars, not 5.
