About Gas Sensors
Gas sensors employ diverse technologies: electrochemical sensors measure gas concentration via chemical reactions (e.g., CO, NO2); Metal Oxide Sensors (MOS) detect gases by conductivity changes (VOCs); optical sensors use light absorption/scattering (OPCs for particles, PIDs for VOCs); Nondispersive Infrared (NDIR) sensors analyze infrared light absorption (e.g., CO2); catalytic bead sensors detect combustible gases (e.g., methane); and semiconductor sensors measure conductivity changes (compact and affordable). Each offers unique advantages in accuracy, cost, and target gas detection, catering to varied applications.
