Air Temperature and Relative Humidity Sensor

Model:
HMP60
Item Number:
26996
Warranty:
1 year

Overview

The HMP60, manufactured by Vaisala, probe measures air temperature for the range of -40° to +60°C, and relative humidity for the range of 0 to 100% RH. It uses the INTERCAP® capacitive RH chip. This field-replaceable chip eliminates the downtime typically required for the recalibration process.

Key Advantages

Accurate, Rugged
Ideal for long-term, unattended applications

Product Notes

requires solar radiation shield for air temp

Benefits

  • Field-replaceable humidity chip eliminates recalibration downtime
  • Compatible with most Campbell Scientific dataloggers
  • Can be mounted to a tower/tripod mast or crossarm

Compatibility

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.
