    Infrared Thermometers FAQs

    What does “distance to spot ratio” mean?

    The laser spot needs to be showing inside the target area. A 9:1 “distance to spot ratio” means you are measuring a 1” diameter area at a distance of 9 ”.

    How far can I measure?

    Distance is unlimited. The size of the target area sets the limit on distance for accurate measurements. Example: If the area you wish to measure is 1 foot in diameter, then you will need to be within 8 feet torecord an accurate temperature.

    What is the smallest target I can read?

    Approximately one-half inch in diameter.

    How do I turn the laser on and off?

    While holding the Power On button down you cantoggle the Lock On button for either laser on or laser off operation. When the laser is activated the laser displays this icon.

    What is emissivity?

    This is a ratio of an object’s infrared emission compared to a theoretical black body, considered 1. Emissivity is always less than 1. Adjustable emissivity allows your non-contact thermometer to be adjusted to the surface you are checking to make readings more accurate.

    How do I adjust the emissivity of my contact/noncontact 375, 376, 377?

    The 375, 376, and 377 feature adjustable emissivity and contact probe capability. This is very useful for determining the emissivity of any surface condition.Simply use the contact probe and record surface temperature. Next use the IR gun and adjust the emissivity until the temperature matches the reading of the contact probes. Copper pipe produces different emissivity properties, ranging from 0.02 to 0.78, due to oxygen oxidation and curvature. You will now have the most accurate reading in the IR mode for that surface.

    How can I make measurements more accurate if I don’t have my contact probe or have a fixed emissivity thermometer?

    Painting the surface being measured matte black will make temperature readings more accurate. A piece of black tape can also be used.
