How to make a standard solution to calibrate?
Completely empty the powder into a clean 250ml glass beaker.
Add 250ml of PH Buffer Powder to the beaker.
Still until the powder has completely dissolved.
PH solution accuracy is ±0.01PH.
Power on?Press the MODEL/CAL button ? Adjust to pH mode?Put the electrode into pH4.01 / pH6.86 / pH9.18 standard solution?Press and hold the MODEL/CAL button for several seconds?The value of pH4.01 / pH6.86 / pH9.18 is no longer flashing, and the calibration of pH4.01 / pH6.86 / pH9.18 is completed.
