e) Prevent the accumulation of condensation water at the level of the sensor leads. Install the
probe so that the probe tip is looking downward. If this is not possible, install the probe horizontally.
Insufficient probe immersion typically creates errors in the measurement of both humidity and temperature
and may even cause a malfunction.
 Standard 100 mm (3.9”) probe: this probe is generally not suitable for through wall installation and is
designed for full immersion in the environment to be measured. At least 15 to 20” of the probe cable
should be inserted together with the probe.
 Optional 250 mm (9.8”) probe: this probe is designed for through wall installation. To facilitate probe
installation and removal, we recommend using a probe holder mod. QMA-15. This holder is a mounting
flange that is equipped with a compression fitting.
Installation Note: You may want to provide an orifice at a distance of about 3” from the probe of the transmitter
for future use by a reference probe and HygroPalm indicator.
