Review on High Accuracy Pocket Size Digital PH Tester Pen for Water Hydroponics - 0.01 PH Measurement Range Ideal for Household Drinking, Pools, and Aquariums (Blue) by Carla Anderson

Hooray, got around to writing yet another review. This time I will tell you about a more accurate measurement of ph (hydrogen index) using an electronic ph meter. Before that, I already wrote how you can find out the ph of water. Now let's move on to a more accurate device, in which the error is minimal - 0.1. This is what the fixture looks like: Of all that was presented on the market in terms of price and quality, it is the best. Yes, ph devices are expensive, unfortunately (from 2 thousand) and I could not find something better in this range. Of course, there is a device for 1.5 thousand, but there will be no automatic calibration - which already complicates the measurement process. Here is the ph of my tap water: The Wato meter is calibrated by 2 points, it is 6.86 and 4.01. 2 points allow you to calibrate the device more accurately. It works on 2 batteries. The device is sold already calibrated. This is how we find out the ph of draft beer :) I hope you liked my review!
