The calibration screw is not functioning, the inflated temperature indication is 1.5 - 3 degrees Celsius in the same environment during the measurement, the electrode immersed in the calibration liquid at the pH 7 of SERA/ pehameter indicates pH 7, A calibration cannot be performed for the reason given above. I have been using the pH measurement in the aquariums of the Voltcraft metro for 7 years and so far it has performed flawlessly. Last year, I replaced the electrode because of the damage.
