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.
- SoC (System-on-a-Chip) Technology -- Complete IR design incorporated on a single chip, creating compact and lightweight design.
- Innovative optical lens -- high accuracy measurements over wide temperature ranges. 12:1 distance to spot (D:S) ratio.
- Laser pointer -- Simply point at desired target and press the trigger for temperature reading.
- External temperature port can extend the temperature up to 1999 °F.
- High- and low-pass filters with audible alarms for out-of-range measurements.
- Temperature modes -- Maximum (MAX), Minimum (MIN), Difference (DIF), and Average (AVG) temperature modes.
- Visual low battery indicators; requires two AAA batteries.
