The ATIR3  infrared temperature head includes an 8:1 cone of view and a laser sight  for quick temperature measurements in english or metric units.

Non-contact Infrared Temperature Accessory with Laser Sight– ATIR3

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, DL3 data logger, and EHDL1 electronic handle to a one-piece infrared, or IR, thermometer. Use the optional Fieldpiece ADLS2 deluxe silicone test leads or the AHDL1 adapter handle with the ATIR3 for use with DMMs with industry standard jacks.
