Introduction
The Fluke Model 65 Infrared Thermometer ("the thermometer") is
a noncontact thermometer with laser pointer. The thermometer
determines an object's surface temperature by measuring the
amount of infrared energy radiated by the surface.
Noncontact thermometers can be used to measure surface
temperatures that are unsuitable for traditional contact
measurement methods (such as moving objects, electrically live
surfaces, and difficult-to-reach objects).
Box Contents
Thermometer, holster, carrying case, 2 AA alkaline batteries (not
installed), Instruction Sheet, Quick Reference Card, and
Registration Card.

  • Page 6: Optical Resolution

    Optical Resolution Optical resolution (also called "Field of View" or "Distance-to- Spot-Size Ratio") is the ratio of the thermometer’s distance from the object’s surface to the size of the area measured ("spot size"). The closer the thermometer is to the object, the smaller the spot size.

  • Page 7: Measuring Temperatures

    Measuring Temperatures Read the section "Ensuring Accuracy " before measuring temperatures. Check that the batteries are installed and the laser switch is in the on position. (See the sections "Installing the Batteries" and "Setting the Switches.") To take a measurement: If the emissivity of the object is different from 0.95, apply black tape, black matte paint, or black magic marker to the object if it is safe to do so.
