In industrial sectors such as chemical, environmental protection, and mining, gas leaks often pose serious safety hazards. This is especially true for highly corrosive and toxic gases like hydrogen chloride (HCl). Once leaked, these gases not only endanger human health but can also cause equipment corrosion and environmental pollution. Therefore, achieving accurate and reliable monitoring of hydrogen chloride gas has become a crucial aspect of industrial safety management.

MQ-E3-HCl Electrochemical HCl Sensor

    Tensensor's MQ-E3-HCL hydrogen chloride gas sensor is a high-performance detection solution designed to address this need. This sensor employs a constant-potential electrolysis principle, linearly measuring hydrogen chloride concentration by detecting the current generated by the gas reaction on the electrodes. It features a measurement range of 0–20 ppm and a resolution of 0.1 ppm, maintaining high sensitivity even at low concentrations, making it suitable for early warning of gas leaks in various industrial settings.

    Furthermore, MQ-E3-HCL sensor exhibits excellent anti-interference capabilities and stability. Even in the presence of common interfering gases such as carbon monoxide, nitrogen dioxide, and chlorine, its response error remains under control. The sensor boasts a rapid response time of ≤30 seconds and a wide operating temperature range of -20℃ to 50℃, enabling continuous and stable operation in harsh industrial environments and ensuring the reliability of monitoring data.

    In practical applications, the MQ-E3-HCL can be widely deployed in chemical plants, waste gas treatment systems, and underground work areas to monitor changes in hydrogen chloride concentration in the air in real time and link with alarm systems for immediate leak detection. Its compact structure and low power consumption facilitate integration into various fixed or portable detection devices, providing users with flexible gas safety monitoring solutions.

    Notably, this sensor also features a 2-year lifespan and supports long-term stable output, reducing the frequency of equipment maintenance and replacement, effectively lowering operating costs. Following standard operating procedures during installation and use—such as avoiding direct welding, preventing electrolyte leakage, and keeping the inlet surface clean—can further extend the sensor's lifespan and performance.

    In today's increasingly safety-conscious industrial environment, choosing a reliable gas sensor is not only about protecting equipment but also about ensuring the health of personnel and safeguarding the production environment. The MQ-E3-HCL hydrogen chloride sensor, with its high accuracy, strong anti-interference capabilities, fast response, and long lifespan, has become an ideal choice for industrial gas monitoring.

    Safety is paramount, and accurate monitoring is essential. The MQ-E3-HCL hydrogen chloride gas sensor uses technology to safeguard industrial air quality, injecting intelligent sensing power into safe production.
