Installation¶
For best measurement results, please consider the following points:
If installed through a wall, make sure the probe is inserted as far as possible into the environment being measured.

During installation, make sure that no condensation can collect on or in the probe and cause a short circuit at the sensor connections. Probes should be installed with the sensors at the bottom. This allows waste heat from the electronics to escape upward. If not possible, then horizontal installation is also acceptable.
