Relative Humidity and Air Temperature

Use the EHT durable RH/temperature sensor with soil moisture probes in microclimate and evapotranspiration studies.

Compact

This 3 cm x 1 cm sensor is able to fit into the smallest of spaces.

Weatherproof

Thanks to its unique Teflon screen, the relative humidity sensor can survive a deluge. Naturally, it won't be transmitting accurately while waterlogged; but as soon as it has it dried out, it's back in the game.

Fast Response

The Teflon screen protects the sensor from liquid water and dust without limiting diffusion of water vapor. The protected sensor is still able to quickly respond to changes in humidity.

Integrated Temperature for Accuracy

Accurate relative humidity readings require accurate air temperature readings taken at the same place and time. This sensor takes both measurements simultaneously for the best possible accuracy.

Radiation Shield Included

The included radiation shield is designed to improve air temperature readings by minimizing radiation and maximizing airflow over the surface of the sensor. Specially designed to preserve the correlation between actual air temperature and sensor air temperature while keeping the shield size small.
