About FLIR

GF304

The FLIR GF304 is a gas imaging camera which was especially developed for the detection of refrigerant gases without the need to shut down the operation. 

The FLIR GF304 is a gas imaging camera which was especially developed for the detection of refrigerant gases without the need to shut down the operation. 

Refrigerant gases are used worldwide in industrial refrigeration systems for production, storage and retailing of food. Refrigerant gas is also used in the chemical, pharmaceutical and automotive industries and in air conditioning systems. Keeping an industrial refrigeration system running is of great importance due to the value of the cooled goods.

Furthermore, replacing or recharging gas can be a costly exercise. Although refrigerant gases are vital for many industries they can also be dangerous for the environment and may be governed by local regulations. That is why it is of the utmost importance to find leaks quickly and easy.

Cooled detector

The FLIR GF304 contains a cooled Quantum Well Infrared Photodetector (QWIP) and a cold band pass filter that allow to visualize gases in the 8.0-8.6 micrometer waveband. It will not only make refrigerant gases, but also the smallest of temperature differences, clearly visible.
