* Temperature compensation in calibration mode: Temperature affects the reaction potentials for all chemicals differently. True ORP is the direct measurement of electron activity during an oxidation-reduction reaction, regardless of temperature. However, for maximum accuracy and ease of calibration, the Myron L Company has developed three calibration standard solutions with known dissolved species. We derived the temperature compensation (from 15șC to 30șC) for those solutions, and embedded automatic temperature compensation into the calibration function of your PT3. Note: To verify calibration while in measurement mode, you must manually correct for any variation in temperature. Example: @25șC, ORP2602OZ calibration solution will read 260mV, however @ 20.0șC ORP2602OZ will read 265mV.
Standard Solutions for calibration:
The ULTRAPEN™ PT3 requires Myron L Company 80mV Quinhydrone, 260mV
Quinhydrone, or 470mV MLC Light’s ORP Standard Solutions for wet calibration and
Sensor Storage Solution for proper storage.
