Latest company news about Selection Guide of Gas Leak Detection Products

Customers often encounter the following problems when developing gas leak thermal imager based on thermal imaging detector and infrared camera module:


-Which detector should be selected to detect specific gas?

-How to detect gas leaks with low gas concentration and slow gas flow rate?

-How to accelerate the development progress and grasp market opportunities?


GSTiR provides customers who are involved in optical gas imaging industries with infrared detectors, cooled AD modules, infrared camera cores, offering multiple choices for manufacturers with different integration capabilities.


So, how to choose a suitable optical gas imaging products?


1. Gas Detection Types


First of all, it is necessary to clarify the type of gas that needs to be detected. Gas detection types are determined by spectral response range. So, customers should select the infrared detector with corresponding spectral response range according to different gas types.


GSTiR cooled MWIR infrared detectors and thermal modules covers wavelength from 3.2μm±0.1μm~3.5μm±0.1μm and other types of gas detection products such as CO, CO₂, SF6 etc. can also be customized according to the needs of customers.
