The SR Series Infrared Thermometer is a self contained spot pyrometer which does not require remote electronics. Temperature signal processing and conditioning is done within the sensing head of the unit.

The SR Series of infrared thermometers feature:

• Stand alone ratio (two-color) infrared thermometer
• Choice of nine models measuring temperatures from 1300° to 6500°F (700° to 3500°C) within discrete temperature ranges
• Choice of fast response time 0.01 seconds or (0.1,1.0 or 10.0 seconds)
• Choice of optical resolution (D/50, D/100, D/150 Range Dependent)
• Choice of output signal (4-20mA or 10 volts)
• Focusable, thru-the-lens viewing
• No moving parts or filter wheels
• Both detectors read the target simultaneously
• Signal/Power supply termination box
• 2 foot or 4 meter Inter-connecting cable
• No separate signal processing electronics required, making this instrument cost effective
• E-slope adjustment on temperature sensor
• Invalid alarm indicator lamp and relay contact closure

Covered by U.S. Patent Numbers 4,919,505 and 5,011,296.

SR SERIES SPECIFICATIONS
Temperature Measuring Range:
1300 to 6500°F (700 to 3500°C)

Calibration Accuracy
Within 0.75% of full scale temperature or 5°F (3°C), whichever is greater

Repeatability
Within 0.3% of full scale temperature

Response Time
(To 95% of full scale output)
0.1, 0.01, 1.0, or 10.0 seconds, as selected

Analog Output
(Referenced to ground) 4-20 mAdc (500 ohm max.) or 0-10 Vdc (<=1 ohm source, 5 mA max.)

Spectral Response
Two adjacent wavelength bands: 0.70 to 1.08 microns and narrow band centered at 1.08 microns

Ambient Temperature Range
(Without auxiliary cooling) 30 to 130°F (0 to 55°C)

Power Supply Requirements
±15 Vdc at 200 mA - Standard
