ORP/Redox Sensor Calibration

Every ORP/Redox probe will read a slighly different level due to its fabrication. You may decide to use it as is or calibrate it. To calibrate the ORP/Redox sensor takes a few minutes and can’t be rushed. You may use either powder in water, a ready made ORP solution or use your pool’s water and test it with either drops or reading paper and use that to define the ORP/Redox value.

The first step is to access the calibration screen and place the ORP/Redox sensor in the solution or water with a known ORP/Redox value.

Then you just wait. Time to let the Redox stabilize.

In the top field, you must enter the calibration value. 750 is an example, but must be confirmed as the actual value or replaced by the correct value.

Below that, you have two buttons, one will apply the calibration and the other will reset it, returning to the natural reading of the ORP/Redox sensor.

Again below that, you have some values to help you.

Stabilized ORP/Redox is a calibrated value averaged over a few minutes.

Calibrated ORP/Redox is the real time reading with calibration applied

Current calibration is the correction applied to the natural reading to get to your calibration.

Original ORP/Redox is the value naturally read by the sensor on which we apply the calibration to get the other values.
