ATIR3 Fieldpiece Infrared Temperature Accessory Head - IR Temperature Head. Infrared Temperature for Surfaces. The Fieldpiece Non-contact Infrared Temperature Accessory with Laser Sight, model ATIR3, collects infrared energy (IR) and converts it to a mVDC signal that is proportional to the temperature being measured. The temperature measured is the average of all the temperatures in the 8:1 cone of viewability. The closer you are to the target, the smaller the area measured. The further away, the larger the area. The digital, non-contact ATIR3 converts the Fieldpiece “Stick” series meter, or electronic handle to a one-piece infrared, or IR, thermometer.

Designed for HVACR professionals, the Non-contact Infrared Temperature Accessory with Laser Sight, model ATIR3, measures infrared energy in it’s cone of view and converts it into temperature readings on your meter using the mVDC scale.
