SIL-111-SS: Standard Field of View Commercial Infrared Radiometer Sensor

$405.00

The SIL-111 is an unamplified analog sensor with a voltage output and 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.
