In industrial production and transportation sectors, internal combustion engines serve as core power equipment. Monitoring and controlling their exhaust emissions remain paramount for environmental protection and safety. With increasingly stringent environmental regulations and rising demands for equipment operational efficiency, precise detection of various components in internal combustion engine exhaust has become an industry imperative. Among these, ammonia (NH₃) stands as a critical pollutant. Accurate measurement of its concentration not only determines compliance with environmental standards but also directly impacts engine performance optimization and fault diagnosis.

　　However, in the complex scenario of internal combustion engine exhaust analysis, customers face formidable challenges: not only must they handle ammonia (NH₃) concentrations as high as 10,000 ppm, but they also need to precisely capture the target gas under extreme conditions where sample gas temperatures reach 500°C, while effectively avoiding measurement deviations caused by other interfering gases and high-temperature water vapor. Traditional equipment often struggles to balance high-temperature tolerance with interference resistance, leading to distorted measurement data, reduced device lifespan, and even disruptions to the entire process flow.

　　Addressing this industry pain point, Yiyuntian Eranntex leveraged its deep technical expertise and profound understanding of customer needs to launch the MS500—a portable ammonia detector specifically engineered for harsh environments. It is not merely a portable detection device but a comprehensive solution integrating high-temperature sampling, precise separation, anti-interference algorithms, and intelligent data processing. From its inception, the MS500 was developed around the core principle of “remaining stable and reliable in extreme environments,” committed to providing users with authentic, trustworthy gas concentration data to help them confidently tackle complex detection challenges.

　　After thorough evaluation and comparative analysis, the client selected the Yiyuntian Eranntex MS500 Portable Ammonia Detector not only for its outstanding technical specifications but also for the professional approach and service philosophy demonstrated by Yiyuntian Eranntex.
