SKU: ERANNTEX Portable Pump-Suction 4-in-1 Gas Detector
The Eranntex BTYQ-MS400 Portable pump-suction 4-in-1 gas detector features three switchable display modes: simultaneous display of four-channel gas concentrations, large-font cycling display of a single channel, or real-time concentration curve visualization. Automatic or manual cycling between channels is supported. Users can customize the display of maximum, minimum, and average values and choose between real-time or timed monitoring modes. The system offers multi-dimensional alarm mechanisms, including audible, visual, combined audible, visual, and vibration alarm modes. It supports concentration thresholds, low-battery warnings, and fault alarms, with multiple settings including low/high limit alarms, interval alarms, and weighted average alarms. The device integrates automatic zero-point tracking technology to effectively eliminate zero-point drift over time. It also features a built-in multi-level calibration routine with an automatic interception function for calibration errors and supports factory reset. An optional temperature and humidity monitoring module is available, and the RS485 communication interface is customizable. OEM/ODM services are also available.
