Overview
The HMP60-ETS is the replacement part for newer ET107 stations. The sensor cable terminates in a connector and is the ideal length for attachment to the ET107 ETo Weather Station. The HMP60-ETS includes an adapter that allows the sensor to fit in a MetSpec radiation shield.
The HMP60-ETS 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 MetSpec 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. It is a double-plated shield that can help reduce the likelihood of nesting insects.

Compatibility
This sensor is compatible with newer ET107, T107, and WSPRO2 stations.
Note: The HMP60-ETS includes an adapter that allows the sensor to fit in a MetSpec radiation shield. The MetSpec radiation shield has wingnuts on the bottom of the shield. If there are no wingnuts, the appropriate replacement sensor for your ET107 station is the HMP60-ET.
