22.11 FLIR GF304 24° Fixed lens
P/N: 59602-0102

General description
The FLIR GF304 is an infrared camera for optical gas imaging (OGI) that visualizes and pinpoints leaks
of refrigerant gases, without the need to shut down the operation. This portable camera also greatly im-
proves operator safety, by detecting gases at a safe distance, and helps to protect the environment by
tracing leaks of environmentally harmful gases.
Refrigerant gases are found in, for example, the food, chemical/petrochemical, and automotive industries,
as well as in air-conditioning systems.
Benefits:
• Improved efficiency: The FLIR GF304 reduces revenue loss by pinpointing even small gas leaks
quickly and efficiently, and from a distance. It also reduces the inspection time by being able to scan a
broad area rapidly without the need to interrupt the industrial process. The wireless connectivity of the
camera allows you to connect to smart phones or tablets for the wireless transfer of images or the re-
mote control of the camera. The FLIR GF304 can also be used for temperature measurement, which
makes it even more useful for predictive maintenance.
• Increased worker safety: The leak detection of gases can be performed in non-contact mode, and
from a safe distance. This reduces the risk of the user being exposed to invisible and potentially harm-
ful or explosive chemicals. With a FLIR GF304 gas-imaging camera it is easy to scan areas of interest
that are difficult to reach with conventional methods. The camera is ergonomically designed, with a
bright LCD and a tiltable viewfinder, which facilitates its use over a full working day.
• Protecting the environment: Several refrigerant gases have a high global warming potential and are
usually governed by regulations. Even small leaks can be detected and documented using the FLIR
GF304 camera.
Detects the following refrigerant gases: R404A, R407C, R410A, R134A, R417A, R422A, R507A, R143A,
R125, R245fa.
