    Introduction The Fluke Ti20 Imager (hereafter, “the Imager”) is a state-of-the-art, lightweight, pistol- grip style thermal imaging unit. Using the Imager, you can obtain instant and accurate thermal images and radiometric readings from distant targets. The Imager is ergonomically designed for right-hand or left-hand use, and captures thermal images and data with a simple trigger press.

  • Page 35: Environmental Conditions

    Environmental Conditions Watch for environmental conditions in the working area. steam, dust, smoke, etc., can prevent accurate measurement by obstructing the path between the target and the Imager optics. Noise, electromagnetic fields, or vibration are other conditions that can interfere with temperature measurements, and should be considered before starting temperature measurements.

  • Page 36: Emissivity

    Ti20 Users Manual Emissivity Emissivity is the measure of an object's ability to emit infrared energy. The hotter an object, the more infrared energy it will emit. Emissivity can have a value from 0 (shiny mirror, perfect reflector) to 1.0 (blackbody, perfect emitter). Most organic, painted, or oxidized surfaces have emissivity values close to 0.95.

  • Page 37: Reflected Temperature Compensation

    Reflected Temperature Compensation Targets that have low emissivities will reflect energy from nearby objects. This additional reflected energy is added to target’s own emitted energy and may result in inaccurate readings. In some situations objects near the target (machines, furnaces, or other heat sources) have a temperature much higher than that of the target.

The increase in time (beyond the normal system response) for the sensor to return to within 5 % of the lower temperature is defined as the stare time.

  • Page 57: Basics Of Infrared Measurement

    Appendix B Basics of Infrared Measurement Q. Why use non-contact infrared thermometers? Non-contact infrared (IR) thermometers use infrared technology to quickly and conveniently measure the surface temperature of objects. They provide fast temperature readings without physically touching the object. The temperature is shown on the LCD display.
  • Page 58 Ti20 Users Manual Gamma X-Rays Ultraviolet Rays 0.1 A 1 UA 100 A Q. How to assure accurate temperature measurement? A. A solid understanding of infrared technology and its principles lies behind accurate temperature measurement. When the temperature is measured by a non-contact device the IR energy emitted from the measured object passes through the optical system of the thermometer or thermal imager and is converted to an electrical signal at the detector.
