An open-path gas detector for explosion-proof acquisition in Japan. It can accurately detect hydrocarbon gases at distances of up to 150 meters (path length), enabling wide-area monitoring.
The IR5500 is a long-range gas detector that uses infrared open-path technology to detect flammable hydrocarbon gases such as methane and propane in real-time with high accuracy. It has a split configuration with a transmitter and receiver, covering a wide range of up to 150 meters (path length). It can handle small leaks at the ppm level to large-scale leaks at the LEL level, making it ideal for outdoor facilities such as chemical plants, oil refineries, and LNG terminals. In addition to a fast response time of under 3 seconds, it features a fail-safe design with self-diagnosis capabilities and automatic gain control, making it resistant to rain and dirt, ensuring stable detection. It is calibrated at the factory, eliminating the need for zero calibration on-site, significantly reducing maintenance burdens after installation. It has obtained Japanese explosion-proof certification, allowing for safe use in harsh outdoor environments. Additionally, it supports Modbus RTU and HART communication, enabling easy integration with control systems. With 4-20mA analog signals, relay outputs, and LED displays, reliable status monitoring and control can be performed both on-site and in the control room.

Company information
Sunny Trading has consistently specialized in the import and sales of automatic control and labor-saving equipment since its establishment in 1961, actively introducing the latest high-performance machinery and equipment from Europe and the United States to the domestic market. The components for production machinery that we handle are widely adopted in industries such as machinery, electrical, and chemical, and we take pride in our extensive delivery track record to national government agencies, universities, research institutions, and the aerospace industry. The delivered parts are incorporated into machines to complete large production facilities, but confirming the compatibility of the products is essential for this process. We always strive to provide appropriate products by investing technical know-how and time for specification confirmation between overseas manufacturers and our customers. Additionally, we take responsibility for follow-up services, including on-site inspections of delivered products and maintenance. Unlike general trading companies that simply import and sell goods, we pride ourselves on being a trading company with engineering capabilities. Products are commercialized as machines by manufacturers, and they are actively utilized in core industries such as semiconductors, steel, shipbuilding, aerospace, packaging, logistics, and chemicals.
