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 ModelThe 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
