The white filter on the probe covers the PEROXCAP sensor. The filter is made of porous PTFE that allows ambient air to reach the PEROXCAP sensor while protecting the sensor in strong or turbulent air flow.

CAUTION The filter is an essential part of the measurement. If the filter is broken, dirty, or removed altogether, measurement does not work as intended.

  • Do not touch the filter with bare hands. If you need to touch the filter, always use clean gloves (rubber, cotton or similar material).

  • Keep the filter free of any grease or oil.

  • Do not touch any parts under the filter. Touching parts under the filter may damage the sensors.
