Introduction Of Portable Co,H2s,O2,Ch4/lel Multi 4 Gas Detector
The detector can simultaneously display four kinds of gases or one kind of numerical indicators of the gas. The index of gas to be detected exceeds or falls below the set standard, the instrument will automatically conduct a series of alarm action, flashing lights, vibration and sound.
The detector has two buttons, a LCD display associated an alarm devices (an alarm light, a buzzer and vibration), and a micro USB interface can be charged by a micro USB; additionally, you can connect the serial extension cable through an adapter plug (TTL to USB)to communicate with a computer, calibration, set the alarm parameters and read alarm history. The detector has real-time storage to record real-time alarm status and time.
