- Make sure there is a minimum clearance of 5 m (16.5 ft) between the probe body and any possible humidifier. Avoid installing in a location where condensation can fall on the sensor inside the duct.
- 2
- When installing the transmitter, drill a second hole approximately 30 cm (12 in) from the installation hole, towards the direction of the air flow, and plug it with a removable seal. This second hole is intended for later use in reference measurement with another device when calibrating or adjusting the transmitter.

Check that the duct diameter is suitable for the probe body (see Transmitter dimensions). Ideally, the sensor (probe head) should be installed in the middle of the duct.
- 4
- Maximum air flow speed: 50 m/s (with sintered filter).
- 5
- Avoid installing the transmitter in dead legs. Supersaturation can occur in areas where there is no air flow.
- 6
- Do not install the probe in a downward angle. Condensation can travel to the sensor along the probe body if the probe points down.
- 7
- Install the probe in a 90° angle so that the sensor is placed as close to the middle of the duct as possible.
