Probe Mounting Clamp
The optional mounting clamp (Vaisala order code: 226067) makes it easy
to install the probe on the wall of the measurement environment. The
probe can be detached for calibration simply by loosening the lower
screw.
Installing the entire probe in the measurement environment prevents heat
conduction to the sensor, and is the recommended installation method.

CAUTION
Attaching the probe mounting clamp to a conductive wall material
should be avoided, since the potential galvanic connection to the power
supplies and uncontrolled earth current loops could cause measurement
errors or even damage to the HMT130 transmitter
