To use a pH meter, the pH electrode is first calibrated with standard buffer solutions with known pH values that span the range being measured. 1. pH Calibration. Turn the meter's power on by pressing the "power" button. Attach the automatic temperature compensation (ATC) probe if it is Calibrating a pH Meter Make sure the meter is in pH mode For a 3 point calibration, use high pH (--), pH 7.0 and low (-.0) solution Before calibration, rinse probe thoroughly with de-ionized water or a rinse solution Immerse the end of the probe completely in the calibration solution Stir the probe gently to Regularly calibrating your pH meter adjusts the electrode reading based off any changes, and ensures that your readings are accurate and repeatable. Also known as a two-point or multi-point calibration, bracketing consists of calibrating to two pH points, one above and one below your expected pH range. Flow meter calibration is the process of comparing the pre-set scale or metering of a flow meter to a standard scale of measurement and adjusting its metering to conform to the standard. Calibration is an essential aspect of instrumentation in a broad range of industries that require high-accuracy Equipment Needed: ph Calibration Protocol & Data Sheets notebook YSI Model 60 ph Meters ph 7 & 10 buffer bottles from kits Purified water Kimwipes ph 4 3. Test each freshly calibrated meter s field standards and record results. 4. If a new Lot # of ph buffer was put into use: After calibration, test the Before use pH meter must be calibrated. Each pH electrode used for measurements is slightly different and its characteristic changes with aging. pH meter calibration is more often referred to as pH electrode calibration , as parameters set are not device dependent, but electrode dependent. Featuring a three-point calibration method with simple calibration procedures, the Dr.meter pH testing device can automatically identify the calibration liquid to give you the pH reading almost in a flash. ? ?Convenient pH Value Reading?: Get the job done with ease. The frequency of calibrating a pH meter depends on usage and possible contamination. The higher the usage and the amount of contamination, the more often you need to calibrate your pHmeter. Ensure a pH meter calibration twice a month to avoid measuring errors. pH Meters and Electrodes There are several types of pH meter in use within the labs. All work on the same underlying principles, and have similar calibration and measurement protocols. In general, you will need the appropriate pH calibration solution(s) (buffer solutions made up to pH 4.00, 7.00, or Calibration of pH meter. 10,028 views. 1. Janine V.
