ECT Air Temperature Sensor

Measure air temperature

The simple ECT Air Temperature Sensor is an easy-to-use research-grade sensor for measuring the temperature of air (when used with the radiation shield), or other materials. (For all-in-one weather monitoring, see the ATMOS 41 weather station).

Weatherproof for long-term use

The sensor is completely waterproof, submersible, and designed for continuous outdoor use.

Plug and play technology

The ECT can be used with either the Em5b logger or the EM50/EM60/ZL6 data logger series.  However, typical EM50/EM60/ZL6 series logger users prefer to measure humidity in conjunction with their air temperature measurements using the ATMOS 14 Vapor Pressure, Temperature, Barometric Pressure, and Relative Humidity sensor, instead of the ECT Temperature Sensor.
