Infrared Thermometer Model CA870
CHAPTER 3
SPECIFICATIONS
3.1 Electrical Specifications
Temperature Range:
-4° to 500°F (-20° to 260°C)
Display Resolution: 1°F/°C
Accuracy:
±2% of reading or ±6°F (3°C), whichever is greater @ 64.4 to 82.4°F (18
to 28°C) ambient operating temperature.
Temperature Coefficient:
Changes in accuracy operating temperature above 82.4°F (28°C) or below
64.4°F (18°C): ±0.2% of reading or ±0.36°F (0.2°C), whichever is greater.
Response Time: 1 second
Spectral Response:
6 to 14μm nominal
Emissivity: Preset @ 0.95
Detection Element: Thermopile
Optical Lens: Fresnel Lens
Field of View (FOV) ratio:
10:1 (Distance : Diameter)
The FOV is the ratio of the
distance to the target to the
target diameter. When the
target diameter is small, it is
important to bring the ther-
mometer closer to the target
to ensure that only the target
is measured, excluding the
surroundings. Remember that the measurement size is one-tenth the dis-
tance to the target. For example, if the thermometer is at 10", then the size
measured is 1".
