Infrared Radiometer Meters

Apogee Instruments Infrared Radiometers (IRRs) measure surface temperature by converting thermal energy radiated from any surface in its field-of-view (FOV) to an electrical signal with a response time less than 1 second. Each IRR carries an impressive uncertainty of 0.3°C at 95% confidence to ensure accurate measurements. The resilient 8-14 µm germanium window corresponds to the atmospheric window in order to minimize the effects of water bands below 8 µm and above 14 µm. The radiation shield, included free of charge with every IRR, insulates your sensor from rapid temperature changes, thus reducing noisy measurements.

The sensor has following special features:

  • Digital (SDI-12) output enables expanded usage regarding number of sensors as well as compatible dataloggers
  • Most accurate infrared radiometer on the market
  • Measures surface temperature rapidly
  • Uncertainty of 0.2°C (95% confidence)
  • Radiation shield included
  • Multiple field of view (FOV) options
  • Calibrated target temperature range from -30 to 65°C
  • Rugged and lightweight
  • Four year warranty
  • Model
