Description
High-Accuracy Measurements
All Apogee IR sensors are NIST traceable and include a calibration certificate. Sensors are calibrated to a custom blackbody cone. Research-grade sensors feature a measurement uncertainty of ± 0.2 C from -30 to 65 C when the sensor (detector) temperature is within 20 C of the surface (target) being measured. Commercial-grade sensors have a measurement uncertainty of ± 0.5 C from 0 to 50 C when the sensor is within 20 C of the surface. Radiometers are only sensitive from 8 to 14 µm (atmospheric window) to minimize the influence of water vapor and CO2 on the measurement.
Field-of-View Options
Research-grade sensors come in five fields-of-view, which includes three circular and two horizontal apertures. Commercial-grade sensors comes in a single 22° half-angle field-of-view option
