Typical applications include plant canopy temperature measurement
for use in plant water status estimation,
road surface temperature measurement of determination of icing conditions,
and terrestrial surface (soil, vegetation, water, snow)
temperature measurement in energy balance studies.
Measurement Range -60 to 110 C *Uncertainty has been determined for ranges below
Calibration Uncertainty (-30 to 65 C), when
target and detector ΔT are <20 C 0.2 C
Calibration Uncertainty (-40 to 80 C), when
target and detector ΔT are >20 C 0.5 C
Measurement Repeatability Less than 0.05 C
Long-term Drift Less than 2 % change in slope per year when germanium filter is maintained
Response Time 0.6 s, time for detector signal to reach 95 % following a step change; meter firmware averaging results in a
3 s response for digital output on meter screen
