Ideal for long-term, unattended applications
Overview
The HMP60, manufactured by Vaisala, probe measures temperature for the range of -40° to 60°C, and relative humidity for the range of 0 to 100% RH. It is suitable for long-term, unattended monitoring, and is compatible with all Campbell Scientific dataloggers.

Detailed Description
The HMP60 uses the INTERCAP capacitive RH chip. This chip is field-replaceable, which eliminates the downtime typically required for the recalibration process.

Additional Compatibility Information
Mounting
When exposed to sunlight, the HMP60 must be housed in a 41303-5A, 41303-5B, or RAD06 6-plate naturally aspirated radiation shield. The 41303-5A and RAD06 attaches to a crossarm, mast, or user-supplied pipe with a 2.5 to 5.3 cm (1.0 to 2.1 in.) outer diameter. The 41303-5B attaches to a CM500-series pole or a user-supplied pole with a 5.1 cm (2.4 in.) outer diameter.
The RAD06 uses a double-louvered design that offers improved sensor protection from driving rain, snow, and insect intrusion, It also has lower self-heating in bright sunlight combined with higher temperatures (> 24°C [~75°F]) and low wind speeds (< 2 m s-1 [~4.5 mph]), giving a better measurement.
