Apogee Instruments - EE08-SS: Air Temperature & Relative Humidity Sensor

Brand: Apogee Instruments

The Apogee EE08-SS is a research-grade air temperature and relative humidity sensor that provides the accurate inputs needed to calculate vapor pressure deficit (VPD), a critical metric for crop steering. It outputs 0 to 2.5 V DC on a 5 m cable.

Pair the EE08-SS with an Apogee fan-aspirated radiation shield (TS-series) for the most accurate canopy temperature and humidity readings, free from radiant heating error.

Key Features

• Measures air temperature and relative humidity for VPD
• 0 to 2.5 V DC analog outputs
• 5 m cable with rugged connector
• Compatible with Apogee TS-series aspirated shields
• Built and calibrated in Logan, Utah; NIST-traceable, made in the USA, and backed by an industry-leading 4-year warranty.

Why Choose This Model

The EE08-SS delivers the accurate temperature and humidity data that VPD-based crop steering depends on, in a sensor built for long-term deployment.

Ideal Applications

• VPD monitoring and crop steering
• Greenhouse and grow-room climate logging
• Integration with aspirated radiation shields
