SI-111-SS is a high-precision infrared temperature sensor with voltage output. The sensor has a 22 ° half angle field of view and a response time of 0.6 seconds. The sensor includes an IP68 marine grade stainless steel cable connector located 30 cm from the head to simplify the disassembly and replacement of the sensor for maintenance and recalibration.

Thermopiles and thermistors both output millivolt signals that most of our data loggers can measure.The data logger uses the Stefan Boltzman equation to correct the effect of sensor body temperature on the target temperature. The calibrated reading has an excellent accuracy of ± 0.2 ° C within the range of -10 ° C to+65 ° C.

Typical applications include: plant canopy temperature measurement for estimating plant water status, road surface temperature measurement for determining icing conditions, and ground (soil, vegetation, water, snow) temperature measurement in energy balance research.
