The measuring instrument has a probe that can be calibrated exactly. For this purpose we supply you with 2x ready-to-use calibration liquid and a handy screwdriver.
Operating Instructions pH tester
- Remove the cover cap.
- Switch on the device at the upper switch.

Maintenance and storage
If you have not used the pH tester for a long time and the measuring diode has been exposed to air, the display may show the values slowly and not regularly. You should then leave the pH tester with the measuring diode in the water for a few hours.
