    Overview

    A SUCH Shop CO detection sensor is a device used to monitor carbon monoxide levels and trigger ventilation control when CO concentration rises. This electrochemical CO sensor provides 0-300ppm measurement, <30s response, ±5%FS accuracy, and RS485/0-10VDC/relay output for smart control systems. It is suitable for underground garages, buildings, offices, mechanical rooms, and indoor CO safety applications.

    Feature

    CO detection sensor feature

    • The complete carbon monoxide sensing and control system employs a multi-level control approach: Local control (at the unit), distribution panel control, individual unit control, and central control. A selector switch is provided at each control level to choose the desired control mode.
    • A unique digital switching function enables intelligent interlocking between the CO sensor and exhaust systems. Should CO concentrations exceed safe limits, the system automatically activates exhaust equipment to maintain indoor air quality at safe levels.
    • The SUCH CO controller features simple and reliable installation requiring minimal additional complexity.
    • As a controller device, the CO concentration sensor enables intelligent interlocking functionality, maximizing energy savings while ensuring CO levels remain within safe operating ranges.

    FAQ
    ❯

    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.
