Robinair TIF7612 Infrared Thermometer PRO with 12:1 Distance To Spot Ratio
Infrared Overview:
Infrared is the name given to a range of electromagnetic wavelengths longer than visible light but shorter than microwaves (1-100 microns). See accompanying figure for details. Infrared thermometers do everything from verifying the temperature in your AC system in the car or home to helping electricians to find an overcharge in electrical systems. Recent advances in optics make this technology more accurate and cost-effective.
How Infrared Thermometers Work:
To measure a surface temperature, the user aims the IR Thermometer at the target, presses a button, and reads the temperature display. The device has an optical lens that collects the radiated infrared energy from the object and focuses it on the detector. The detector converts the energy into an electrical signal that's amplified and displayed as a temperature reading. An infrared thermometer measures temperature by sensing the magnitude of radiated energy at infrared frequencies. Using this data and the actual temperature of the detector, the thermometer calculates the temperature of the surface that emitted the energy.
