MQ2-CO-Ф14×5 is a high-precision fuel cell type CO electrochemical sensor developed by Shanxi Tengxing, certified with UL approval. It can directly replace international brand gas sensors without PCB modification, ideal for home CO alarm and energy storage fire monitoring applications.

    1. Core Advantages

    UL Certified: Comply with international safety standards, convenient for your product certification and market access in North America, Europe and global markets.

    Pin-to-Pin Replacement: Same dimension Φ14×5, matched resistance parameter and circuit design as foreign-brand sensors. No redesign of circuit board or firmware, fast switching from imported parts to cut procurement cost and shorten delivery cycle.

    Outstanding Performance: Measuring range 0~5000ppm (max 10000ppm), resolution 1ppm, T90 response＜30s, linear output, repeatability＜3%, service life up to 10 years. Stable working at -10℃~50℃ (occasional -20℃~60℃), humidity 15%~90%RH. Low zero drift under wide temperature changes.

    Strong Anti-interference: Low cross-sensitivity against most common interfering gases like H₂S, NO₂, ethanol, methanol etc., effectively reduce false alarm rate. Low power consumption with high sensitivity.

    2. Key Application Fields

    (1) Residential CO Alarm

    Perfect for household carbon monoxide detectors used for heater, boiler and indoor fuel equipment safety monitoring. Fast response detects tiny CO leakage timely to ensure home safety, adaptable to various household temperature & humidity environment.

    (2) Energy Storage System Monitoring

    Widely used in container energy storage cabinet and battery energy storage fire detection. Detects CO generated from battery thermal runaway in real time; wide temperature tolerance fits severe working conditions of energy storage stations, long service life lowers later maintenance expense.
