The multi gas monitor has a built-in 2400mAh large-capacity lithium battery with a Type-C interface supporting 5V/1A fast charging, integrating charging and communication functions. It is equipped with a color LCD screen and 5 multi-function buttons for simple operation; parameter modification features a WYSIWYG mode, and the multi gas detector also supports short-press for quick data saving, making it easy for beginners to use.
Comprehensive data management for efficient storage and export. The multiple detector has a built-in 12M flash memory that can store 120,000 pieces of historical data and 30,000 pieces of alarm data, supporting customizable storage intervals and manual quick data saving. With USB U-disk mode for direct PC connection, data is exported in CSV format. The multi-gas detector 4 gas-compatible system also allows viewing of multi-dimensional data such as STEL/TWA time-weighted values and extreme values, enabling comprehensive data traceability.
Intelligent alarm & multi-functional configuration for all-round safety protection. The portable multi gas detector supports high and low dual alarms for gas concentration plus one-click emergency alarm; the alarm sound can be quickly muted and restored, with optional vibration reminder. It also supports temperature and humidity calibration, three-level calibration of gas sensors, and WiFi remote data upload. The multi gas detector provides all-round protection for working environments while meeting the needs of equipment calibration and remote data management.
