The Portable Multifunction Gas Analyzer features a modular sensor design, allowing installation of up to four 6-in-1 sensor modules simultaneously. Each module is fully plug-and-play, with snap-in connections for both the gas path and communication interfaces, enabling convenient replacement and maintenance.
The instrument is equipped with a 5-inch high-definition color touchscreen, a capacitive touch interface, and runs on an Android operating system that supports OTA (Over-The-Air) remote wireless upgrades.
It supports various customized functions to enable regional networking, interconnection, and remote wireless data transmission, including MESH communication for remote video transmission in confined spaces. Monitoring data can be uploaded to a cloud platform, allowing users to access real-time information through a mobile APP. Remote alarms can also be sent via phone calls, SMS, or WeChat notifications.
Various software functions can be customized, including emergency enforcement software and ecological environmental enforcement software, making the device suitable for industrial safety monitoring and environmental inspection applications.
