Specifications
SKU: ERANNTEX Portable Fire Gas Detector
The Eranntex Portable Fire Gas Detector's multiple alarm system supports audible, visual, vibration, or combined alarms, providing comprehensive status indication. It covers three trigger types: concentration threshold, undervoltage warning, and fault alarm. Alarm modes include low limit, high limit, range, and weighted average settings. The device features automatic zero-point tracking technology, effectively preventing zero-point drift caused by long-term use. The calibration system supports multi-level calibration and automatically prevents concentration calibration errors. A factory reset function is standard, and optional features include an ambient temperature and humidity monitoring module and an RS485 communication interface. Other functional expansions and communication protocols are fully customizable, and the device is fully open to OEM/ODM development.
