In the fields of industrial safety production, mine environmental monitoring, and environmental gas detection, reliable and accurate real-time monitoring of phosphine (PH₃), a common toxic and harmful gas, is crucial. Traditional detection methods often face challenges such as slow response, susceptibility to interference, and insufficient stability. The Tensensor's MQ-E3-PH₃ constant-potential electrolytic phosphine gas sensor offers users across various industries an efficient and reliable gas monitoring solution thanks to its superior sensing performance and stable operation.

MQ-E3-PH3 Electrochemical PH3 Sensor

    Accurate and Sensitive, Rapid Response

    The MQ-E3-PH₃ sensor is based on the principle of electrochemical sensing. It generates a current signal through the redox reaction of phosphine and oxygen on the electrode surface, achieving a linear conversion between gas concentration and electrical signal. Its measurement range covers 0–10 ppm, with a resolution as high as 0.05 ppm and a response time of no more than 30 seconds, ensuring rapid early warning at the initial stage of gas leaks and gaining valuable time for emergency response.

    Strong Anti-interference, Stable and Reliable

    The sensor exhibits excellent anti-interference capabilities in complex gas environments. According to cross-interference test data, it exhibits extremely low cross-interference response to various common industrial gases such as carbon monoxide, hydrogen sulfide, and formaldehyde, effectively avoiding false alarms. Simultaneously, the sensor possesses excellent temperature adaptability and long-term stability, maintaining accurate output within a range of -20℃ to 50℃, with a monthly output stability deviation of less than 2%, and a lifespan of up to two years, significantly reducing maintenance frequency and operating costs.

    Reasonable Design, Wide Application

    The sensor adopts a low-power design, supports wide voltage operation, and is compatible with various detection instruments and system integrations. Its compact structure and convenient installation make it suitable for fixed monitoring equipment, portable detectors, and embedded systems. It is widely used in chemical production, grain storage, mine safety, environmental monitoring, and other fields, providing continuous protection for personnel health and production safety.

    Intelligent Protection, Safety First

    In terms of product use and maintenance, the MQ-E3-PH₃ also demonstrates a high degree of user-friendliness and safety design. The sensor has a built-in waterproof and breathable membrane for dust and splash protection; it supports electrode short-circuit storage to extend idle life; and it strictly prohibits soldering installation and contact with organic solvents to ensure that the sensing core is not damaged. Clear precautions and operating instructions further ensure the reliable operation of the product in various harsh environments.

    As a high-precision, high-stability, and highly interference-resistant phosphine sensor, the MQ-E3-PH₃ not only represents the advanced level of current electrochemical gas sensing technology but is also an indispensable "sensory nerve" in industrial safety monitoring systems. Tensensor with its solid technical accumulation and rigorous manufacturing processes, provides a keen and reliable "chemical eye" for global industrial safety and environmental protection.
