Figaro’s TGS5141 is a battery-operable electrochemical sensor that uses a unique electrolyte that eliminates the need for a water reservoir. By eliminating the water reservoir used in TGS5042, the comparative size of TGS5141 is reduced to just 10% of TGS5042. With its ultra-compact size, this sensor is the ideal choice for size-oriented applications such as portable CO detectors, small residential CO detectors, and multi-sensor fire detectors. OEM customers will find individual sensor data printed on each sensor in barcode form, enabling users to skip the costly gas calibration process and allowing for individual sensor tracking.
