4 Maintenance

Clean the sensor with water and a brush without using:

• High-pressure cleaner

• Highly compressed air

• Solvents

• Corrosive/caustic agents

• Alcohol-based disinfectants

During cleaning and disinfection, the sensor should be removed and the sealing plug for the ca-

ble should be mounted. Alternatively, the sensor protective cap can be mounted. The sensor

must be placed with the tip pointing upwards during disinfection.

After the sensor has been exposed to water and condensation, it requires a period where the relative humidity

is lower than 80 %RH in order for it to measure correctly.

Do not bend the sensor as this would inflict permanent damage on the electronics of the sensor.
