WebCheck the pH slope in pH 7 buffer regularly. The slope should be greater than 92% (53.5 mV/pH @ 20°C or 54.4 mV/pH @ 25°C).The offset (as measured in fresh pH 7 buffer) should be +/- 30 mV for new electrodes and +/- 59 mV for aged electrodes to enable auto-buffer recognition during calibration.. How to check your pH electrode slope. Select the millivolt … WebThe Unisense pH micro electrode is a miniaturized glass pH electrode designed for research applications within physiology, biotechnology, environmental sciences, and related areas .
