If you donвЂ™t get good readings from the calibration buffers, I would consider replacing the meter with a good-quality pH meter with the features mentioned above. You should get good readings from the unit as it should be able to maintain calibration for at least a few days if you properly store your probes in the storage solution. What I recommend is to calibrate your unit using the known solutions and then wait a few hours and measure the known solutions again. Calibrating an analog unit is similar, but typically you adjust a different calibration knob for each of the known solutions. In addition, I recommend purchasing electrode storage solution, which is a solution you want to store your probes in to extend their life and maintain calibration.ДЇor a digital pH meter, you simply push the calibration button and then put the probes into each of the fixed solutions when prompted, and the unit will measure each and calibrate the unit. To do this, you need to purchase a вЂњpH Buffer Calibration Kit.вЂќ The kit contains three different solutions with a known pH of 4.0, 7.0, and 10.0. Any pH meter must be calibrated before use. Removable probes let you replace the pH electrodes, as these will wear out and become non-linear within two to three years for a typical unit.ДЄ second source of your problems could be improper calibration of the unit. Some of the features you should look for in a pH meter include an accuracy of +/вЂ“ 0.01 pH, automatic temperature compensation, a good (digital or analog) calibration system, and-ideally-removable probes.

Very cheap ones may not be suitable for beer brewing. Many low-cost meters are not terribly accurate, having variability of +/вЂ“ 0.1 pH or higher. You mention that you purchased an inexpensive pH meter, and this could certainly be the source of your problems. While you can estimate mash pH and make basic adjustments using software, it is still important to have a good-quality pH meter to verify your pH. You mention that you purchased an inexpensive pH meter, and this could certainly be the source of your problems. Managing your mash pH within the 5.25.6 range is important for all-grain brewers. Managing your mash pH within the 5.2вЂ“5.6 range is important for all-grain brewers. A Craft Beer & Brewing Magazine reader recently asked us the following question: I purchased an inexpensive pH meter to manage my mash pH, but IвЂ™m having a hard time getting consistent readings from it?
