Apogee Instruments - Model SI-100-400 -Road Weather Infrared Radiometer

The SI-4HR-SS (SDI-12) and SI-5HR-SS (Modbus) infrared radiometers are developed for road weather networks specifically, with a 10° vertical field of view, allowing for remote detection of a narrow and distant target roadway. The rectangular-shaped aperture maximizes the horizontal field of view allowing for a larger integrated measurement without including undesired target areas such as sky or surrounding terrain. The elongated external shield is designed to better protect from snow and ice building up on the sensor.
