4 Installation
4.1 Wall and Ceiling Mount
Best measurement performance is achieved when the entire probe is located inside the environment to
be monitored.
In such a case, the HTP201 may be for instance fixed onto a wall with the mounting clip HA010211
(for polycarbonate) or HA010225 (for stainless steel, both not included in the scope of supply, see data
sheet “Accessories”), or freely hang from the ceiling on the connection cable.

4.2 Duct Mount
The probe also can be installed into a duct using the plastic flange HA010214 or the stainless steel
flange HA010201 (not included in the scope of supply, see data sheet “Accessories”).

4.3 Recommendations for accurate Humidity and Temperature
Measurement
■
In case the HTP201 probe is not entirely located in the environment to be monitored, large
temperature differences along the probe will lead to temperature gradients. These will have an
influence on the accuracy. Therefore, it is of paramount importance to minimize the temperature
gradients. The biggest part of the probe shall be located in the target environment and the rest shall
be thermally well insulated.
