SGX Solid Polymer Electrolyte Gas Sensors

SGX Sensortech offers advanced Solid Polymer Electrolyte Gas Sensors designed for health protection through smart sensing solutions. These sensors operate on the principle of electrochemical catalytic reaction, delivering a current proportional to gas concentration. Featuring a dry core design with three electrodes in contact with a solid electrolyte, the sensors are ideal for a wide range of applications including indoor air quality monitoring, automotive systems, building safety, and industrial monitoring. Key advantages include ultra-low power consumption, high accuracy, long lifetime, no zero drift, no poisoning, fast response times, and direct linearity. They are designed for wide temperature operation (-40C to +55C) and can function in high humidity environments (15-95% RH) without electrolyte leakage. SGX ensures high volume production capacity with 100% QC through printed production processes, automation, and smart quality control systems.
