Cleaning the Probe
If any impurities such as dust, soot and oil are attached to the sensor, the amount of heat that the airflow
draws from the sensor surface (heat dissipation rate) will change, thus the air velocity reading will be
affected.
The probe must be cleaned when the sensor is contaminated from use in an unclean environment.
Clean the sensor portion of the probe in an
ultrasonic cleaner for approx. 10-20 sec. Do
not clean the sensor longer than required as excess cleaning will lead to sensor damage.
Use tap water (or purified water) for cleaning. The sensor portion can also be cleaned in
a vessel filled with neutral detergent diluted with water, and by stirring it in the vessel.

Make sure to TURN OFF the power before cleaning.

Dry the probe completely after cleaning. Do not use the probe before it is
completely dried.
