SIL-411: Commercial-Grade SDI-12 Digital Output Standard Field of View Infrared Radiometer Sensor

Due to a Covid-related parts shortage, please contact us for availability

The SIL-411 has an SDI-12 digital output and 5 m high-quality cable terminating in pre-tinned pigtail leads for easy connection to dataloggers and controllers. The sensor has a 22° half-angle field of view and a response time of 0.6 seconds. Typical applications include plant canopy temperature measurement for use in plant water status estimation, road surface temperature measurement of determination of icing conditions, and terrestrial surface (soil, vegetation, water, snow) temperature measurement in energy balance studies.
