The New FLIR T420 Thermal Imaging Camera
Flexible, Innovative and High Quality Professional-Grade Handheld Thermal Cameras
FLIR’s T-Series represents thermal imaging’s most ergonomic and flexible hand-held cameras. It features a rotating optical block that lets you point the lens up or down along a 120° axis while keeping the large 3.5” (89mm) color touchscreen relaxed at eye level. Scan targets from tough angles without stress.
Using a high resolution sensor with 320 X 240 pixels the T420 infrared cameras arm users with superior infrared imaging resolution that works harder to reveal trouble spots.
The new T420 is a substantial upgrade from the previous T400 series, utilizing a new parallax based auto-focus which operates at twice the speed of traditional auto-focus in thermal cameras.
Other versatile imaging capabilities include scalable picture-in-picture and thermal fusion for easier image identification and added context.
