High-accuracy, non-contact surface temperature measurement
Apogee Instruments' infrared radiometers combine high accuracy, durability, and low cost.
Calibrated to a custom black-body cone with 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. 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
Four field of view (FOV) options, including: three circular and one horizontal aperture. Custom FOVs available upon request.
Anodized aluminum body with fully-potted electronics. The radiation shield reduces thermal fluctuations.
Analog and digital output options are available. Analog versions include un-amplified and amplified voltage outputs. Digital versions include SDI-12 communication protocols.
Plant canopy temperature measurement for use in plant water status estimation, road surface temperature measurement for determination of icing conditions, and terrestrial surface (soil, vegetation, water, snow) temperature measurement in energy balance studies.
|Warranty and Support
All Apogee products are backed by an industry-leading four year warranty and outstanding customer support.
