  • Description

    Wind speed and direction

    The Davis anemometer isn’t revolutionary—it’s all about simplicity. It measures wind speed and direction over your chosen measurement interval without complex setup, maintenance, or programming.

    Straightforward setup

    Setup is simple: mount with two screws, orient with a compass, plug into the logger, and start logging wind data.

    Wind: a critical soil moisture variable

    Wind is one of the main variables that determines how fast water moves through the soil-plant-atmosphere continuum. With the Davis anemometer, you can add this important variable to your soil moisture data set without a lot of hassle.

ECT Air Temperature Sensor

    ECT Temperature Probe
    Radiation shield for more accurate measurements
  • Description

    Measure air temperature

    The simple ECT air temperature sensor is an easy-to-use sensor for measuring the temperature of air (when used with the radiation shield) or other materials.

    Weatherproof for long-term use

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

    Plug and play technology

    The ECT can be used with either the EM5b logger or the EM50 logger series.  However, typical EM50 series logger users prefer to measure humidity in conjunction with their air temperature measurements using the VP-4 Vapor Pressure, Temperature, Barometric Pressure, and Relative Humidity sensor, instead of the ECT Temperature Sensor.
