Overview
The HMP60-ETR is the replacement temperature and RH sensor for older ET stations. The sensor's cable terminates in a connector and is the ideal length for attachment to the ET107 or ET106 ETo Weather Station. The HMP60-ETR includes an adapter that allows the sensor to fit in a R. M. Young radiation shield.
The HMP60-ETR 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.

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.
The radiation shield is a 41303-5A shield modified to mount to an ET station. This six-plate naturally-aspirated radiation shield has a louvered construction that allows air to pass freely through the shield thereby keeping the probe at or near ambient temperature.

Compatibility
This sensor is compatible with older ET107, T107, and WSPRO2 stations and retired ET stations such as the ET106, T106, and WSPRO.
| Note: The HMP60-ETR includes an adapter that allows the sensor to fit in an R. M. Young radiation shield. The R. M. Young radiation shield does NOT have wingnuts. If you see wingnuts, the appropriate replacement sensor for your station is the HMP60-ETS. |
