12:1 Wide-Range Infrared Thermometer - General Tools & Instruments

The General Tools & Instruments IRT657 12:1 Wide-Range Infrared Thermometer provides professional technicians and mechanics with a precise, non-contact solution for temperature measurement. This gun-style infrared thermometer accurately and easily measures surface temperatures—including hot, cold, or inaccessible equipment—from a safe distance, ensuring efficiency and safety in diagnostics and maintenance tasks. It is a versatile tool suitable for a broad range of industrial and automotive environments.

Key Features

• Wide Measurement Range: Accurately measures temperatures from -40°F to 1076°F (-40°C to 580°C), making it suitable for extremely hot or cold surfaces in various applications.
• 12:1 Distance-to-Spot Ratio: Enables accurate temperature readings from a safe distance, which is ideal for inaccessible or hazardous components.
• Precision Accuracy: Provides reliable measurements with an accuracy of ±3.6°F (±2°C) or 2% of the reading above 32°F (0°C), and ±5.4°F (±3°C) or 2% of the reading below 32°F (0°C).
• Fast Response Time: Delivers a 95% response in just 250 to 500 milliseconds for quick diagnostic work.
• Large Backlit LCD: Features a 1.6-inch diagonal backlit LCD for clear readability of measurements in diverse lighting conditions.
• Star Burst Laser Targeting: Helps users approximate the size of the measured spot, resulting in quick and accurate temperature measurement.

Applications

This versatile infrared thermometer is essential for professionals across numerous fields.

• Automotive Diagnostics: Quickly identify overheating components such as engines, exhaust systems, catalytic converters, radiators, and brakes, as well as diagnose HVAC system issues and fluid leaks.
• HVACR: Troubleshoot ductwork, refrigerant lines, compressors, and detect air leakages or imbalances in heating and cooling systems.
• Industrial Maintenance: Monitor bearing temperatures, electrical panels, motors, boilers, furnaces, and production processes to prevent downtime and equipment failure.
• Building/Facilities Maintenance: Locate insulation deficiencies, hot spots, or moisture issues, and assess air leakage in commercial and residential properties.
• Electrical Troubleshooting: Safely check for hot spots in wiring, circuit breakers, and connections to prevent electrical hazards.
