The Bebur AS-300 fixed multi gas detector is a gas detection instrument that can continuously and online detect the concentration of multiple gases in the ambient air. The instrument adopts catalytic combustion/electrochemical /PID/ infrared NDIR principles, capable of simultaneously detecting 1 to 4 types of gases. It can transmit the real-time gas data detected on-site via RS485 signals. It is a modular gas detector with on-site LCD display and plug-and-play sensor replacement, meeting the application requirements of different industries.
