Calibration Test Powder Packets For PH Pen Calibration Solution :
PH Pen Calibration Solution Calibration Method :
1. Firstly, 6.86 calibration powder is poured into 250ml distilled
water or pure water and stirred well. Then, the power of PH pen is
turned on and the test end is put into the calibration solution.
2. See if the PH pen shows 6.86 or 6.8 in the correction solution of 6.86. If it does not show 6.8 or 6.86, adjust the screw in the screw hole on the back of the PH pen with a random screwdriver and set the value to 6.86 or 6.8 (0.1 to 6.8)?
3. Find a new cup, the same 250 ml of pure water or distilled
water. Pour the correction powder of 4.01 red packaging bag into
it, mix it well, and put the PH pen corrected just now into the
correction solution of 4.01.
4. 4.01 or 4.0 value indicates that the correction is
successful, if the display is not 4.01 or 4.0, it needs to be
revised in the same way as before.
