The SR Series Infrared Thermometer is a self contained spot pyrometer which does not require remote electronics. Temperature signal processing and conditioning are all done within the sensing head of the unit. The SR Series of infrared thermometers includes both SLR and fiber optics sensors to best fit with your temperature sensing application.

• Stand Alone Ratio (Two Color) Infrared Thermometer
• Focusing SLR or Fiber Optic Versions
• Fast Response Time
• No Moving Parts Or Filter Wheels
• Both Detectors Read The Target Simultaneously

BASIC UNIT - SLR Version consists of self-contained IR Thermometer, Signal/Power Supply Termination Box, 12 foot or 4 meter Inter-connecting Cable, and one detailed Operations Manual.

BASIC UNIT - Fiber Optic Version consists of Fiber Optic IR Sensor, with Fiber Optic Cable and Focusable Reimaging Lens Assembly (Focal range of 10" to infinity), Wiring Terminal, 12 foot or 4 meter Interconnecting Cable, and one detailed Operations Manual. Complete descriptions and specifications for both versions are shown in the Product Bulletin.

Covered by U.S. Patent Numbers 4,919,505 and 5,011,296.
SLR VERSION FEATURES AND BENEFITS

• Completely self-contained two-color infrared thermometer
• Choice of nine models measuring temperatures from 1300° to 6500°F (700° to 3500°C) within discrete temperature ranges
• Focusable, thru-the-lens viewing
• Choice of optical resolution (D/50, D/100, D/150 Range Dependent)
• Choice of fast response time 0.01 seconds or (0.1,1.0 or 10.0 seconds)
• Choice of output signal (4-20mA or 10 volts)
• 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

FIBER OPTIC FEATURES AND BENEFITS
The SR Fiber Optic Infrared Thermometer provides all features of the SLR Version plus the following:

• Compact, stainless steel, focusable reimaging lens assembly fits in tight places, withstands environments to 400°F (200°C) without auxiliary cooling. Two focusable ranges of 6" to 10" (150 - 250mm) or 10" (250mm) to infinity are available
• Extension tip withstands ambient temperatures to 575°F (300°C) for high temperature applications
• Various mounting accessories for reimaging lens or extension tip assembly are available for easy mounting
• Optional air purge simply screws to front of reimaging lens to keep lens clean
• Flexible fiber optic cable assembly provides optical link between sensing head and and reimaging lens. Offers lengths of 3 feet to 10 feet as standard, and up to 30 feet as special
• Choice of optical resolution D/30, D/60, or D/30 x D/150 is model selectable
