    2.6 probe filter 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. The filter is an essential part of the measurement. If the filter is broken, ...
