SI-4HR-SS: Research-Grade SDI-12 Road Surface Infrared Radiometer Sensor

$889.00

The SI-4HR-SS infrared radiometer is 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. The SI-4HR has an SDI-12 digital output and high-quality cable terminating in pre-tinned pigtail leads for easy connection to dataloggers and controllers. The sensor has a response time of 0.6 seconds. Sensor includes IP68 marine-grade stainless-steel cable connector 30 cm from head to simplify sensor removal and replacement for maintenance and recalibration.
