Product Specification

Equipped with CH-A3 Catalytic combustion methane sensor module （CH4） AG-3-LEL-CHA3(D) Product Description：

The AG-3-LEL-CHA3(D) is an embedded type module equipped with the Alphasense CH-A3 Catalytic Sensor, capable of detecting combustible gases such as methane (CH4), LP gas, and Hydrogen (H2) in diverse environments. The module has been pre-calibrated before leaving the factory and has good durability, stability, and anti poisoning. It utilizes digital communication through a UART bus output for gas concentration readings, which allows users to easily and quickly integrate the module into various systems. This makes it suitable for industrial gas detection applications
