Endress+Hauser Sensor pH and ORP CPS76D

Clean the sensor before each calibration.

Clean away fouling on the sensor as follows depending on the type of fouling:

Clean with grease remover, e.g. alcohol, as well as hot water and (alkaline) agents containing surfactants (e.g. dishwashing detergent).

2. Lime, cyanide and metal hydroxide buildup and low solubility organic buildup:

Dissolve buildup with diluted hydrochloric acid (3 %) and then rinse thoroughly with plenty of clear water.

Harmful if swallowed. Limited evidence of carcinogenicity. Possible risk of harm to the unborn child. Dangerous for the environment with long-term effects!

Warning: Ensure the sensor is immersed in medium for at least 24 hours before use if stored dry.

Is the sensor stored in a KCl solution (3 mol/l) or buffer solution (pH 7.00)?

Note: Calibration frequency depends on operating conditions (fouling, chemical load).

Note: pH or ORP sensors with Memosens technology do not need to be calibrated when first connected.

Two-point calibration is required for pH sensors.

Is the sensor immersed in a defined buffer solution (e.g. pH 7 or 220 mV)?

Enter the pH value or mV value of the buffer solution.
