• The hot wire air speed sensor of the AP3203.2 and AP3203 probes is heated and, in
case of vapours or gases, could trigger a fire or an explosion. Do not use the
probe in the presence of flammable gases. Make sure that in the environment
where you measure, there are no gas leaks or potentially explosive vapours.
• The probe is fragile and you have to handle it with attention. A simple shock, given that the
sensor is partially protected during its use, make the probe unusable.
• After finishing the measurement, the sensor placed on the probe head must be protected with
the provided threaded protection barrel.
• During the use, AP3203.2 or AP3203 omnidirectional probe has to be protected with the rela-
tive sphere of metal circles.
• Don’t touch the sensors with your fingers.
• For cleaning the probe use only distilled water.
AP3203.2 or AP3203 probe has a spherical
protection scheme. To reduce the encumbrance
when it’s not use, AP3203.2 or AP3203 probe is
supplied with a cylindrical case to screw on the
probe head.
