Product TypeElectrochemical CO Sensor
Gas Sensing for OEM Integration
Product Overview
A low-power, high-precision CO sensor developed for long-life alarms and fixed carbon monoxide monitoring equipment.
The sensing current is generated by the electrochemical oxidation-reduction reaction of carbon monoxide and is proportional to the gas concentration according to Faraday’s law.
Its wide linear range, stable repeatability and UL and EN 50291-1 certification information make it suitable for OEM carbon monoxide alarms and building-safety products.
Designed for Reliable Integration
