SI-431-SS: Ultra-narrow field of view infrared radiometer

The SI-431 has an SDI-12 digital output. The sensor has a 14° half-angle field of view and a response time of 0.1 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. Sensor includes IP68 marine-grade stainless-steel cable connector 30 cm from head to simplify sensor removal and replacement for maintenance and recalibration.
