The device is simple to use and set to the appropriate measurements that one wants to perform. I just needed the pH measurement. 3 packets of buffer packets are provided in dry form. These are each mixed in 250ml of distilled water. The calibration instructions are horrible. I put the pH meter in the whole container of each buffer solution and the pH drifted and drifted and drifted going up and down. Reading on a troubleshooting website, the problem is too big of a sample to analyze for calibration so the unit takes forever to stabilize. The solution is to use a sample size like I did- 30-40ml. This does the trick. The meter is not perfect but does get close to the labelled pH buffer (acidic, close to neutral and alkaline) strength. Push the mode button in for 6 seconds. "CAL" will display and the pH value will flash 3 times then you are good to go. Review: Great for testing water for plants - It does exactly what it says it does, which is measure PH, TDS, EC and Temp. I really only need PH and TDS, but the others are a nice bonus. Most of these that do PH and TDS are very pricey. This one does it all for a great price. It’s even cheaper than the same model that only measures PH, TDS and Temp. I’m guessing that is b/c the other came out first and has more reviews. I also like how it has the automatic temp adjustment for measuring PH. A must have for testing water. ## Features - 【3-in-1 Water Quality Meter】 The tester has the functions of monitoring TDS, pH meter and temperature measurement.
