Xi'an Huafan Portable Composite Gas Detector (4 in 1 gas monitor) is generally equipped with standard gases: combustible gas, carbon monoxide, hydrogen sulfide, and oxygen.
The instrument can be customized as 2-in-1, 3-in-1, or 4-in-1 according to customer needs, and can display up to 4 gas values at the same time. When the index of a certain gas to be tested exceeds or falls below the set standard, the instrument will automatically Sound, light and vibration alarms can be released manually. It is suitable for detecting the concentration of gas in the ambient air. It is widely used in metallurgy, power plants, chemicals, mines, tunnels, tunnels, underground pipelines and other places to effectively prevent accidents. It is a multi-gas detection and alarm instrument that can be flexibly configured.
The portable composite gas detection and alarm instrument can detect four kinds of poisonous and harmful gases at the same time. It is small in size, safe and power-saving, with full Chinese display and easy operation. The gas detection instrument has 2 buttons, an LCD display and related alarm devices (alarm lights, buzzer and vibration), and has a miroUSB interface, which can be charged with a charger with a miroUSB interface; it can also be plugged into a USB Connect the TTL adapter to the host computer to read the alarm record. The composite gas detection and alarm instrument itself has a real-time storage function to record the alarm status and time in real time.
