Gas detector

Portable 4-in-1 gas detector XDB-CD4

One, four in one gas detector features:

1. At the same time, the concentration of methane, hydrogen sulfide, oxygen and carbon monoxide is detected. (Customized gas types such as: NH3, SO2, CO2, HCL, CL2, PH3 and other gases.)

2, this instrument is a safety equipment, explosion-proof mark Exibd I, can be used in flammable and explosive environment dangerous environment.

3, the operation is simple and convenient, human-machine interface is clear and easy to identify.

4, alarm point can be set according to user requirements, two audible and visual alarm function.

5, the instrument uses 4 bright alarm lights. 1 charging indicator, easy to charge, 5V, USB can be charged.

6, with parameter backup function, you can restore factory Settings. Prevent misoperation.

7. Crocodile type back clip is adopted to effectively prevent the instrument from falling. Also equipped with a leather case.

8, continuous working time, more than 12 hours.

9, there is a data storage function, you can set the saving interval, save up to 1900 data.
