13.5 FLIR K53
P/N: 72203-0511
Rev.: 41168
General description
The FLIR K53 is a robust and reliable infrared camera designed to perform under extremely severe condi-
tions. The FLIR K53 has an intuitive interface with a design that makes it easy to control even with a
gloved hand. The crisp and clear image helps you to navigate through smoke and to make quick and ac-
curate decisions.
Benefits:
• Robust and reliable: The FLIR K53 is designed to meet tough operating conditions. It can withstand a
drop from 2 m (6.5 ft.) onto a concrete floor, is water resistant to IP67, and is fully operational up to
+85°C (+185°F), or +260°C (+500°F) for 5 min.
• Clear and crisp thermal images: The maintenance-free uncooled microbolometer sensor produces
clear and detail-rich images of 320 × 240 pixels which have been further improved with FSX, a digital
image processing enhancement technique. Thermal images are presented on a large, bright 4″ dis-
play, helping you to navigate and to make quick and accurate decisions.
• Easy-to-use—also in a gloved firefighter’s hand: An intuitive and simple user interface allows you to fo-
cus on the job. The FLIR K53 can be controlled by just one large button on top of the unit. Ideal for a
gloved firefighter’s hand.
