Review on π Enhance Your Display Quality with 7Pros Backlight Resolution Calibration Measurement by Fernando Beck
Reliable and easy to use
This is my second meter from 7Pros. The first was a few years ago and I still use it today. I find manual calibration much easier and more reliable. It comes with 4 bags of calibration powder, which is very easy to calibrate and accurate. The reading tends to stabilize after about 4 seconds. I use it to adjust the pH of the water for my plants. Everything you need is in the box including batteries and a great water test kit.
- EASY MEASUREMENTS AND ACCURATE RESULTS: Liquid tests in seconds. Just turn on the meter, dip it into the test solution, wait a few seconds for the reading to stabilize, and capture the results - done! The meter offers a full pH measurement from 0-14 with a resolution of 0.01 and an accuracy of 0.1 pH
