The Eranntex BTYQ-PTM600-CH4-TDLAS Portable Methane Analyzer's multiple alarm system supports audible, visual, vibration, or combined alarm modes, providing three-dimensional status indication. It covers three trigger types: concentration threshold, undervoltage warning, and fault alarm. Alarm modes include low limit, high limit, interval, and weighted average settings. The device is equipped with automatic zero-point tracking technology and multi-level calibration functions, effectively suppressing zero-point drift caused by long-term use and automatically intercepting concentration calibration errors. A factory reset function is standard, and an ambient temperature and humidity monitoring module or RS485 communication interface are optional. Other functional expansions and communication protocols support in-depth customization, and are fully open to OEM/ODM cooperation and development.
