This best multi gas detector enables accurate 5-in-1 multi-gas detection and covers various hazardous gases. Equipped with multiple sensing technologies including electrochemistry, infrared and catalytic combustion, the multi gas analyser can precisely detect 5 types of gases: flammable gas, oxygen, hydrogen sulfide, carbon monoxide and carbon dioxide. It meets the one-stop multi-gas detection needs of diverse scenarios with accurate and highly stable detection data.

Explosion-proof, rugged and portable design for complex working environments. Adopting a PC+TPU plastic overmolding process for the shell, the portable multi gas detector is drop and shock resistant, with a compact body of only 142.5×78.2×41.6mm and a weight of 380g for easy carrying. Compliant with explosion-proof standards, the handheld multi gas detector can work normally in the temperature range of -20~+65℃, humidity ≤95% and Zone 1/2 explosive gas hazardous areas, suitable for complex scenarios such as warehousing, mines and tunnel construction sites.

Large-capacity battery life & user-friendly interaction for hassle-free operation. 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.
