Simple PH Meter Automatic Temperature Compensation 0.1 Resolution

Automatic Temperature Compensation 0.1 Resolution Simple PH Meter :

Notes For Simple PH Meter :
1. Keep away from direct sunlight or high temperatures.
2. Battery replacement requires recalibration.
3. Avoid collisions or falls.
4. Frequent use of electrodes requires frequent calibration.
5. High measurement accuracy requires frequent calibration.

Simple PH Meter Calibration Method :

For very precise work the pH meter should be calibrated before each measurement. For normal use calibration should be performed at the beginning of each day. The reason is that the glass electrode does not give a reproducible e.m.f. over longer period of time. Calibration should be performed with at least two standard buffer solutions that span the range of pH values to be measured. For general purposes buffers at pH 4.01 and pH 9.18 are acceptable.

1 Immerse the electrode in PH 6.86 standard buffer solution and gently shake the electrode.
2 After about one minute, regulate the trimmer with a screwdriver until the buffer solution value corresponding to the measurement.
3 Immerse the electrode in PH 4.01 or PH 9.18( the standard buffer solution).
4 After about one minute, regulate the trimmer with a screwdriver until the buffer solution value corresponding to the measurement .
