MI-210: Standard Field of View Infrared Radiometer with Handheld Meter

Infrared Radiometers

Product Description

The MI-210 has a 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.


Specifications

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

Stability (Long-term Drift):

less than 2 % change in slope per year when germanium filter is maintained in a clean condition

Response Time:

0.6 s, time for detector signal to reach 95 % folloing a step change; meter firmware averaging results in a 3 s response for digital output on meter screen
