Probe Mounting Clamp
The optional mounting clamp 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. You can order a single
clamp (Vaisala order code 225501) or a set of 10 clamps (226067).
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 HMT120 transmitter.
