Duct or channel mounting

When the probe is installed in a duct or channel, it is recommended to

use the optional mounting flange (GM45156SP).

1. Drill a hole with minimum diameter of 22 mm in the wall.

2. Attach the flange onto the duct with four screws so that the gasket

ring seals the attachment.

3. Place the probe through the flange so deep that the perforated

head is completely in the duct (see Figure 5).

NOTE

If the air pressure in the duct is clearly lower than in surroundings, an

additional sealing may be necessary. This is to avoid possible

measurement errors due to leakages through the joint.
