320x256 / 30μm Cooled Infrared Camera Module with 55mm Lens for VOCs Gas Leak Detection
Volatile Organic Compounds, or VOCs, are gases that are emitted into the air from products or processes. Some are harmful by themselves, including some that cause cancer. In addition, they can react with other gases and form other air pollutants after they are in the air.
GAS330 is a cooled infrared thermal imaging module specially designed for gas leakage detection. It integrates 320x256 / 30µm MCT cooled MWIR infrared detector and utilizes spectral wavelength filtering technology to visualize the invisible VOCs that cannot be seen by naked eyes.
Camera manufacturers can design their own gas leak detection camera based on this module easily and efficiently.
Global Sensor Technology is a supplier of infrared detectors sensors and OEM thermal camera cores. We have more than 10 years of experience in the infrared thermal imaging industries. We have professional after-sales service team to provide customers with professional reply. For any questions or problems, please contact us at any time, we will be in the first time for you to answer.

The GAS330 gas leak detection thermal imaging camera is used for visiualizing the invisible VOCs (volatile organic compounds) and detecting gas leakage such as: Methane, Ethane, Propane, Butane, Pentane, Hexane, Heptane, Octane, Ethylene, Propylene, Isoprene, Methanol, Ethanol, Butanone, Benzene, Toluene, Xylene, Ethylbenzene etc.
1. What is NETD?
NETD refers to "Noise Equivalent Temperature Difference". It is a measure for how well a thermal imaging detector is able to distinguish between very small differences in thermal radiation in the image. NETD is typically being expressed in milli-Kelvin (mK). Usually the lower the NETD figure is, the higher the thermal sensitivity indicates.
2. What is OGI (Optical Gas Imaging)?
Optical gas imaging is the method of using thermal infrared cameras to visualize gas, including methane and many other organic gases. Thermal cameras for gas leakage are fast-acting gas leak detection devices which can conduct non-destructive testing and protect the safety of inspectors.
3. What are the key considerations on an infrared detector / thermal module for your application?
---The detector resolution
---The pixel size
---The NETD
---The image quality
---The lens options
---The power consumption
---The size and weight
---The mechanical & electrical interface
---The budget
