In industrial production and environmental protection, the concentration monitoring of hydrogen fluoride (HF), a common but highly corrosive and toxic gas, is particularly important. Leaks or excessive concentrations not only endanger human health but also cause irreversible damage to equipment and the environment. Therefore, selecting a stable, sensitive, and reliable hydrogen fluoride sensor has become an indispensable part of industrial safety and environmental monitoring.

MQ-E3-HF Electrochemical HF Sensor

    Tensensor's MQ-E3-HF hydrogen fluoride sensor, designed based on the constant potential electrolysis principle, possesses excellent detection performance and wide applicability, making it an ideal choice for hydrogen fluoride gas monitoring in industrial and environmental fields.

    Precise Detection, Rapid Response

    The MQ-E3-HF employs electrochemical sensing technology. Hydrogen fluoride gas undergoes a redox reaction within the sensor, generating a current signal proportional to its concentration. This results in high detection accuracy and a short response time (T90 ≤ 90 seconds). Its measurement range covers 0–10 ppm, with a resolution of 0.1 ppm and a maximum measurable range of 100 ppm, meeting diverse needs from environmental monitoring to industrial leak early warning.

    Stable and Reliable, Strong Anti-interference

    This sensor exhibits excellent repeatability (<2%) and long-term stability (monthly drift <2%), and boasts wide temperature and humidity adaptability (-20℃ to 50℃, 15% to 90%RH). It exhibits superior cross-interference performance and extremely low response to common industrial gases such as carbon monoxide and methane, significantly improving the reliability of monitoring data.

    Low Power Consumption Design, Easy Integration

    The sensor's recommended load resistance is only 10Ω, resulting in low power consumption suitable for long-term continuous monitoring. Equipped with standard pins and test circuitry, the MQ-E3-HF facilitates embedding into various gas detectors, fixed monitoring systems, or portable devices, enabling rapid deployment and system integration.

    Resilience in Harsh Environments

    The MQ-E3-HF features a waterproof and breathable membrane protection structure, allowing for stable operation in non-condensing humidity environments. Its robust casing and high protection level make it suitable for various scenarios including chemical, semiconductor, metallurgical, and environmental monitoring, maintaining stable output even in industrial environments with acidic gases and complex gas compositions.

    Intelligent Early Warning for Prevention

    Combined with IoT or on-site monitoring systems, the MQ-E3-HF enables real-time transmission, historical recording, and alarm for exceeding limits of hydrogen fluoride concentration. This helps enterprises build intelligent gas safety monitoring networks, upgrading from "post-event response" to "pre-event prevention."

    Choosing the MQ-E3-HF is not just choosing a sensor, but also choosing a responsibility for safety and a commitment to the environment. Precise sensing and intelligent protection ensure that hydrogen fluoride has nowhere to hide. Would you like to know more of our products, pls feel free to contact us:
