320x256 30μM Thermal Camera Core Cooled IR Camera Module For Gas
Leak Detection
GAS330 by GST Infrared
320x256 / 30μm Cooled Infrared Camera Module with 55mm Lens for
VOCs Gas Leak Detection
Product Description
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

FAQs
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 is infrared thermal imaging?
In nature, all objects whose temperature is higher than absolute
zero (- 273 ℃) can radiate infrared rays. By using the infrared
camera detector to measure the infrared radiation temperature
difference between the target itself and the background, you can
get different infrared images, which are also called thermal
images.
4. How do infrared detectors work?
Infrared radiation that emitted by target enters the sensing range
of the thermal detector, then the infrared detector converts the
radiation signal of different intensity into the corresponding
electrical signal, and then through amplification and video
processing, forms the infrared image that can be observed by the
naked eyes.
5. What are the advantages of cooled infrared detectors?
The cooled infrared focal plane detector operates at a low
temperature which is provided by a detector dewar cooler (ddc). It
has high sensitivity and can distinguish more subtle temperature
difference than uncooled infrared detector. It can detect, identify
and recognize objects at a very long range which is more than ten
kilometers away. The structure of cooled detector is very complex
which results in a relatively high cost than uncooled detector.
