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. A 6° telephoto lens option is available to ensure accurate temperature measurement of small targets from farther distances.
