6 reviews for Amprobe IR-450 Infrared Pocket Thermometer

  1. Bbatman

    The best IR thermometer I’ve every owned

    I’ve owned almost every brand o IR thermometer.
    This one for the money is the best.
    It also uses common sized batteries.
    You could spend 10 times for a better one but only be a little more accurate.

    ✔ Yes, I recommend this product.

  2. Juicy24

    Amazing tool

    All around a great tool used many times, don’t leave without it. Would recommend to anyone looking for a compact temp reader. Could use a more stronger plastic material.

    ✔ Yes, I recommend this product.

  3. Choclair

    Small size a plus, buttons frustrating

    As a HVAC technician I’ve carried this product around in my jacket pocket for about a year. Using it regularly to check temperatures on diffusers and hanging heaters in manufacturing plants.

    Pro’s: Great size, much less cumbersome then typical pistol style IR guns.The LED light is bright enough to get you out of a pinch, but probably won’t replace your day to day flashlight.

    Con’s: The buttons are difficult to push/hold, not the most durable plastics used.

    While the accuracy isn’t great (8:1 ratio) it achieves its goal of being an ultra portable IR thermometer.

    ✔ Yes, I recommend this product.

  5. medvic

    way off more than 20 degrees off

    Although the product description touts it as an HVAC-R tool, it is too inaccurate. Checked it against several Fluke digital thermometers in the HRA lab where I teach and it is way off.

    ✘ No, I do not recommend this product
