Zobell Solution, ORP Calibrator Zobell Solution is used for calibrating ORP/Redox on several YSI instruments. 0000020400 00000 n Calibration solutions are used for external standard, internal standard, and standard addition approaches to quantitation. Unlike pH, ORP values are affected by all oxidizing and reducing agents, not just acids and bases which only influence a pH measurement. To begin, without calibration your ORP meter will not provide reliable readings of ORP in the solution. It comes from a simple REDOX reaction between the titanium (IV) and iron (II) impurities. The Calibration Kit can be used for 30 calibrations and consists of the following items: (1) pint pH 4 buffer (1) pint pH 7 buffer . Since the pH measuring electrode output changes as the pH of the process changes it acts as a moving reference effectively cancelling out any change in pH and leaving only the mV value which is due to changes in diatomic chlorine (Cl2) levels. So, as the pH increases, an ORP sensor detects a decrease in value which reflecting the decrease in HOCl. When measuring ORP an important feature to remember is that unlike pH, temperature compensation is not normally used for ORP measurements. 0000004609 00000 n endstream endobj 800 0 obj[/Separation/PANTONE#202728#20CV/DeviceRGB<>] endobj 801 0 obj[/Separation/PANTONE#20368#20U/DeviceRGB<>] endobj 802 0 obj[833 0 R] endobj 803 0 obj<>stream Concentrated powder makes 125, 250, or 500mL of calibration standard.
