MI-210 Standard Field of View Infrared Temperature (22º angle)

The Apogee MI-210 Temperature Meter has an standard FOV half angle of 22 degrees and the handheld unit
displays and stores the current target temperature.
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.

Calibration Uncertainty (-20 to 65 C): ± 0.3 C, when target and detector temperature are within 20 C
Calibration Uncertainty (-40 to 80 C): ± 0.5 C, when target and detector temperature are different by more than 20 C
Measurement Repeatability: ± 0.1 C
