Portable Multi Gas Detector

JH-BD- portable gas detector is an instrument that uses pump suction to detect flammable, explosive or toxic and harmful gases. When the concentration of the measured gas reaches the alarm point set by the instrument, the instrument will emit sound and light. , Vibration alarm, alert on-site personnel to take relevant measures according to the actual detection situation.
It adopts high-definition color screen for real-time display, and adopts imported gas sensor, which can detect multiple gases at the same time.

Can detect 6 kinds of gases at the same time;
Rich man-machine interface;
2.8-inch high-definition color screen, displaying real-time concentration, alarm, time, storage and other information;
Standard USB charging interface, with charging protection function, support USB hot swap, the charging state instrument can work normally;
Using 8000mA high-capacity rechargeable polymer battery, it can work continuously for a long time;
A variety of alarm modes, multi-directional three-dimensional indication of the alarm state when alarming;
Alarm methods include: sound and light alarm, vibration alarm, display visual alarm;
Alarm types include: concentration alarm, undervoltage alarm, fault alarm;

Multiple alarm mode settings: low alarm, high alarm, interval alarm;
Misoperation identification function: Concentration calibration misoperation can be automatically identified and prevented, which can avoid defects caused by human factors;
Meet the design requirements of intrinsically safe circuits, anti-static and anti-electromagnetic interference.
