Working Principle:
The gas alarm adopts our company's latest developed environmental air grade intelligent electrochemical sensor, which is plug and play. The instrument monitors the concentration of toxic and harmful gases (leaks) in the workplace in real-time online. If the concentration exceeds the threshold (the instrument has a built-in GBZ2.1-2007 standard threshold, which can be modified by the user), the alarm will automatically activate the workplace ventilation, air exchange or purification device (optional), which can fully ensure the personal and property safety of on-site workers.

　　Instrument features:
The instrument adopts our company's latest developed environmental air grade intelligent electrochemical sensor; (Automatic identification of sensor type, range, calibration parameters, service life, and maintenance time).
The instrument can provide up to 16 gas warning measurements (standard configuration includes 4 gas sensors).
The instrument adopts advanced MEMS flow sensors for real-time online monitoring of sampling flow.
The instrument provides users with various alarm prompts such as sound, light, and electricity.
◆ Rich interfaces (4 switch values, 2 USB ports, 2 serial ports) can provide users with more expansion options.
A brand new human-computer interaction interface, users can set all functions of the instrument through the 15 inch touch screen (standard) of the instrument.
The instrument adopts our company's self-developed maintenance free electrochemical sensor, which is plug and play for users. Users only need to replace the sensor during maintenance, upkeep, and calibration without moving the host equipment.
The instrument is designed in accordance with national EMC and EMI standards.
