A PH sensor.

Name: Gravity: Analog pH Sensor/Meter Kit V2


Calibration: Calibrated against buffer solutions provided in the kit.

Type: Analog

Operational Range: 5 to 60 degrees C

Unit: N/A

Range: 1 to 14

Life Expenctancy: ~0.5 year



There is no set schedule for calibrating. The length of time between calibration is determined by how often the probe is used. It is typically done once a month. More if needed.


It is not recommended to submerge the probe in the measuring liquid for long periods of time.

The probe should be rinsed and cleaned with distilled water, then placed back into the protective sleeve along with a solution of 3M KCl for storage.
