4.1.2 pH Calibration
Remove and place the sensor in a low pH (ie. 4.0) calibration standard solution and tap pH LOW
CALIBRATION
in the uPyxis app. Measure for 1 minute and wait for the measurement result to stabilize
before performing calibration, the low pH calibration standard value range acceptable for this step is 1.00-
6.00 pH.
Place the sensor into the pH 7.0 calibration standard solution and tap pH 7 CALIBRATION in the uPyxis app.
Measure for 1 minute and wait for the measurement result to stabilize before performing calibration.
Place the sensor in a high pH (ie. 10.0) calibration standard solution and tap pH HIGH CALIBRATION in the
uPyxis app. Measure for 1 minute and wait for the measurement result to stabilize before performing
calibration, the high pH calibration standard value range acceptable for this step is 8.00-13.00 pH.
