Overview
Specifications

Apogee infrared radiometers are the most accurate non-contact temperature sensors available anywhere. The SI-4H1 has an SDI-12 digital output. The unique geometry of the SI-1H1 gives a wide 32 degree half angle field of view in the horizontal direction with a 13 degree half angle field of view in the vertical direction. This enables the user to mount the sensor at shallower angles without seeing above the horizon while maximizing the area measured. The sensor has tinned leads for connecting to a datalogger. Applications include measuring the temperatures of road surfaces, plant canopies, and soil, snow and water surfaces. Measurement of surface temperature is a crucial component of energy transfer. Accurate measurement of the leaf-to-air temperature gradient is essential to the determination of transpiration rate and stomatal conductance in both single leaves and plant canopies.
