This high-sensitivity electrochemical CO concentration sensor is available for sale, with a measurement range of 0~300ppm, rapid response (<30s), accuracy up to ±5%FS, and resolution of 1ppm. The CO sensor supports RS485, 0~10VDC, and relay outputs for easy integration with various control systems.
Carbon monoxide detection sensors typically utilize electrochemical principles or infrared absorption principles to measure CO concentration in the air. Electrochemical sensors generate a weak current through chemical reactions between the gas and an electrolyte solution, with the current intensity being proportional to the CO concentration.
A typical detection range for CO sensors is 0–1000 ppm. This specific CO sensor has a detection range of 0–300 ppm. Sensors with higher detection ranges are also available, typically featuring high sensitivity and a low detection threshold (as low as 1 ppm). These enable early warning for trace amounts of CO in the air, allowing users to take ventilation or evacuation measures before concentrations rise, ensuring safety.
To ensure long-term stability and accuracy, it is recommended to calibrate carbon monoxide sensors every 6 to 12 months. Calibration typically involves comparison with standard concentration gases (e.g., 100 ppm CO calibration gas). Some high-end sensors feature automatic calibration capabilities, effectively reducing maintenance frequency.
