Mantra to silence enemiesa pH meter. Example 1: An electrode in pH 7.0 buffer generates +15 mV. When placed in pH 4.0 buffer it generates +175 mV. The net difference between the two buffers is +160 mV, which is then divided by +177.48 mV. The result, 0.901, is then multiplied by 100 to give a slope percentage of 90.1%. Example 2: An electrode in pH 7.0 buffer generated ... calibration standard (e.g., pH 7) has not changed, immerse the probe into the initial standard. Wait for the readings to stabilize. The reading should read the initial standard value within the manufacturer’s specifications. If not, re-calibrate the instrument. If re-calibration does not help, consult the manufacturer or replace the unit. 12.
