Fixing method

The standard product uses a sleeve-type fixing method; see the product dimension drawing. (Flange fixing or bent plate fixing methods are optional.)

Fixing bracket

No standard product is available; 1.5-meter and 1.8-meter brackets are optional (sold separately).

Standard configuration

3-meter cable (10-meter communication cable is optional).

Remarks

The sensor integrating atmospheric temperature, humidity, and air pressure parameters is installed in a three-layer outdoor radiation shield. The radiation shield uses a special ratio of PC and fiber, and the internal heat insulation layer minimizes the impact of solar radiation. With no moving parts, the accuracy of long-term measurement data is guaranteed.
