Test finally arrived

Arrived, test showed the calibration is unstable. Changes over time for an unknown reason. Make sure you calibrate when the device is at room temperature. The room temperature should be close to the normal daily temperature and increased if necessary. I tried minimizing the high-low edge and center to minimize skew. Has been connected to a backup battery with surge protection. Suspicious tolerances of internal components make the device prone to drift. I have endeavored to eliminate earth currents etc.

Pros

COMBINED 2-IN-1 WATER QUALITY MONITOR: Displays temperature and pH measurement results for continuous long-term monitoring
