Specifications

Datalogger Channels:

one differential (thermopile) and one single-ended

(thermistor); please note that our CR200-series

dataloggers are not compatible.

Input Power:

2.5 V excitation for thermistor

Absolute Accuracy:

±0.2°C @ -10° to +65°C; ±0.5°C @ -40° to +70°C

Uniformity:

±0.1°C @ -10° to +65°C; ±0.3°C @ -40° to +70°C

Repeatability:

±0.05°C @ -10° to +65°C; ±0.1°C @ -40° to +70°C

Response Time:

<1 s to changes in target temperature

Target Temperature Output Signal:

60 μV per °C difference from sensor body

Body Temperature Output Signal:

0 to 2500 mV

Optics:

Germanium lens

Wavelength Range:

8 to 14 μm (corresponds to atmospheric window)

Field of View (FOV):

22° half angle. The FOV is reported as the half-angle

of the apex of the cone formed by the target (cone

base) and the detector (cone apex). The target is a

circle from which 98% of the radiation viewed by the

detector is being emitted.

Operating Range: -55° to +80°C; 0 to 100% RH
