FLIR T840

High-Performance Thermal Camera with Viewfinder

The FLIR T840 infrared camera is designed to help electric utility and other thermography professionals comfortably survey equipment both indoors or outdoors and seek out signs of failure all day long. Thanks to an integrated eyepiece viewfinder and a bright 4-inch color LCD display, the T840 makes it easy to conduct inspections outside in bright, challenging light conditions. The 180° rotating lens platform and thoughtful ergonomic design helps users quickly diagnose failing components in hard-to-reach areas. Pair the T840 with a FLIR FlexView™ dual field of view lens for the convenience to instantly switch from wide-area to telephoto scanning. A 6° telephoto lens option is also available to ensure accurate temperature measurement of small targets from farther distances.

The purchase of a T840 camera includes a 3-month subscription to FLIR Thermal Studio Pro and FLIR Route Creator.
