GS022-HC Pyroelectric Hydrocarbon Sensor
It is a dual-channel pyroelectric hydrocarbon (HC) gas detector based on NDIR (Non-Dispersive Infrared) principle. It is mainly used for high-precision detection of hydrocarbon compounds such as methane, propane, and refrigerants.
Features：
Principle: Based on lithium tantalate (LiTaO₃) single crystal pyroelectric effect + CMOS-MEMS technology, it detects hydrocarbon gas concentration through dual-wavelength infrared absorption method.
Package: TO-39 metal case, dual-channel (signal + reference), built-in high-precision thermistor for temperature compensation.
Core Application: NDIR detection and spectral analysis of hydrocarbon gases (CH₄, C₃H₈, refrigerants, etc.).
