The AlphaSense CH-A3 is a high-performance pellistor-based (catalytic bead) gas sensor designed for the detection of combustible gases, including methane, propane, hydrogen, and other hydrocarbons. It is engineered to deliver fast and reliable response in safety-critical applications such as industrial gas leak detection, mining, HVAC, and environmental monitoring systems. The CH-A3 uses a matched pair of active and reference beads for precise signal stability and compensation, ensuring long-term accuracy. With a compact design, high sensitivity, and durable construction, it integrates easily into portable or fixed gas detection systems.
