Overview
The HMP50 measures both temperature and relative humidity and is suitable for long-term, unattended monitoring. The humidity component features a field-replaceable chip, which eliminates downtime typically required for the recalibration process. The HMP50 is compatible with all Campbell Scientific data loggers.

Detailed Description
The HMP50 measures temperature with a 1000 Ohm platinum resistance thermometer (PRT) and relative humidity (RH) with a 50Y Intercap capacitive chip. The chip is field-replaceable, which eliminates the downtime typically required for the recalibration process. This temperature and RH sensor is compatible with all Campbell Scientific data loggers.
The HMP50 should be housed in a solar radiation shield—typically the 41303-5A. The 41303-5A 6-plate naturally aspirated shield attaches to a mast, crossarm, or tower leg.

Additional Compatibility Information
Mounting
The HMP50 is typically housed in a 41303-5A 6-plate naturally aspirated shield.
It may also be housed in a 41003-5 10-plate shield if additional hardware is used. A 41322 Adapter Plate allows the HMP50 to be mounted in the lower part of the 41003-5 10-plate shield. Alternatively, a 41381 extension tube and the 6637 split nut plug can be used to mount the HMP50 in a higher part of the 41003-5; the #41381 cable is also required.
Both the 41303-5A and the 41003-5 attach to a crossarm, mast, or user-supplied pipe with a 1.0-in. to 2.1-in. outer diameter.
