  • Introduction to Infrared Thermometers
    Infrared Thermometer: What is an Infrared Thermometer? An infrared thermometer is a non-contact temperature measurement device. Infrared Thermometers detect the infrared energy emitted by all materials -- at temperatures above absolute zero, (0°Kelvin)-- and converts the energy factor
  • Infrared Thermometers Tutorial
    frequency (or longer wavelength) Anything material above absolute zero (-273.15 degrees Celsius or 0 Kelvin), radiates in the infrared. Even ice emits infrared radiation. WHY CAN'T I SEE INFRARED?. Human eyes are designed for visible light, but two species are known to detect IR: some rattle snakes

  • Non-Contact Infrared Thermometers Frequently Asked Questions
    0.75 to1000 microns. Any object warmer than absolute zero (0 degrees Kelvin) emits energy somewhere within that range. What is an infrared thermometer?. An infrared thermometer (sensor) can take an object's temperature without touching it. Raytek sensors can measure the amount of infrared energy
