Overview
Specifications

Apogee infrared radiometers are the most accurate non-contact temperature sensors available anywhere. The SI-411 has an SDI-12 digital output and comes with a 22 degree half angle field of view. The sensor has tinned leads for connecting to a datalogger. 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.

Input Voltage Requirement: 4.5 to 24 V DC

Current Drain: 1.1 mA (quiescent), 6 mA (transmitting)

Calibration Uncertainty (-20 to 65 C): 0.2 C, when target and detector temperature are within 20 C

Measurement Repeatability: < 0.05 C

Stability (Long-term Drift): less than 2 % change in slope per year when germanium filter is maintained in a clean condition

Response Time: 0.2 s

Field of View: 22° half angle

Spectral Range: 8 to 14 μm; atmospheric window

Operating Environment: -45 to 80 C, 0 to 100 % relative humidity (non-condensing)

Dimensions: 2.3 cm diameter and 6.0 cm length

Mass: 190 g (with 5 m of lead wire)

Cable: 5 m of four conductor, shielded, twisted-pair wire. Additional cable available in multiples of 5 m. Santoprene rubber jacket (high water resistance, high UV stability, flexibility in cold conditions). Pigtail lead wires.

Warranty: 4 years
