- Page 3 CALIBRATION The ORP-200 can take measurements of ORP levels (mV) and temperature. Your ORP-200 meter has been factory-calibrated to a 200 mV buffer solution. While this is suitable for ORP Measurements most applications, it may be necessary to recalibrate the meter for more accurate results. Additionally, it should be noted that ORP buffer solutions may vary amongst manufacturers.
- Page 4 For best measurement accuracy: Hold mode 1. Though it is not necessary, the ORP-200 will be more accurate if calibrated before each use. This is the case with all digital ORP and pH meters. 2. Clean with distilled water or a pH 7 buffer solution after each use, even if checking the same sample.
