Jellas Pocket Size PH Meter / PH Tester / Mini Water Quality Tester for Household Drinking Water, Hydroponics, Aquariums, Swimming Pools, PH 0-14.0 Measuring Range, 0.1PH Resolution (Yellow)
Update: Jellas customer service contacted me and kindly offered a replacement for my broken unit. I was impressed with the speed and service, and I have updated my review from 3 to 4 stars.
Unless you pay 10 times as much or more for a laboratory quality meter, all of these affordable pocket-pen metes like this one will need adjustment for drifts in the reading over time. I bought a kit at the link below with test solutions of known pH, which makes it easy to know if the meter needs adjustment occasionally This meter is easy to adjust with a screw on the back.
About once a month, I simply dip it into a solution of known pH, and adjust the screw slowly if needed until the display shows the correct pH. Other meters that say they are "auto-calibrating" are anything but automatic. They require you to have test solutions of 2 different pH, normally 4 and 6.86. Finding test solutions of the required pH is often difficult or requires messy mixing of exact amounts of powers and distilled water. The auto-correcting ones then require complicated procedures of pressing and holding buttons while you dip the meter in test solutions and clean the meter between in distilled water between each test solution. It is time consuming, messy, and confusing.
Simple meters like this one with an adjustment screw are much, much easier to test and adjust when needed. You simply dip it into a test solution of any known pH, and then adjust the screw if needed until the display shows the correct pH for that test solution. Adjusting one like this with a screw adjustment is no harder than moving the hands of a clock for day-light-savings time, while the "auto-calibrating" meters are more comparable to filing a long-form income tax return on paper without a calculator or PC.
