Ph meter slope percent calibration
Webb30 aug. 2015 · The slope is displayed in a percentage (%) value, with 100% being ideal. When the electrode is new, the slope should be in the upper 90% range. As the electrode ages and loses efficiency, the slope and response of the electrode will start to decrease. The slope value is updated each time a two point calibration is performed and usually … Webb2. To pass calibration, for the 530 and 530-P pH meters, the slope must be 100 ± 5%. If slope is out of range, several corrective . SOP No. EQ-01-09 Date Revised 03-31-20 ...
