Applications:
Portable O2 detector is an intrinsically safe and explosion-proof instrument and is designed to deter O2.
Portable O2 detector is a low-cost, maintenance-free single gas monitor designed to protect personnel from dangerous O2 gas exposure in the most extreme conditions. Despite its compact size, the Portable O2 detector includes features usually found only in larger multi-gas monitors including a large, OLED display, internal audible/visual alarms and simple push-button operation.
The monitor continuously displays ambient combustible gas readings and will alert the user when gas concentrations exceed the preset low or high levels. Added features include adjustable alarm setpoints, calibration gas values, and choice of text-only display selected by the user through a simple, push-button routine. Portable O2 detector also has a peak/hold feature to show the highest reading during a shift and includes a special flip-cap calibration adapter for quick and simple calibration. Portable O2 detector is covered by a two-year warranty from the date of manufacture.
It is used at the underground coal mine and mine safety inspection mainly. Certainly, it is also applied to fire fighting, confined space, chemical industry, oil and all kinds of environment that needed to measure the combustible gas.
| Feature | Benefit |
| 2-year warranty | Lowers the overall cost of ownership by providing a full 24 months of warranty coverage. |
| Weight of 102g | Light weight and compact size, can be worn on the belt, shirt pocket, coveralls or hard-hat. |
| Flip-cap calibration feature | Portable O 2  detector has a unique, built in calibration adapter to make calibration easy and eliminates the need to search for a calibration cup. |
| OLED display | Provides continuous display of the actual concentration of combustible gas  in the ambient environment as well as remaining battery life. |
| Adjustable low and high alarm setpoints | The user can configure Portable  O 2  detector r  to suit a number of different applications. |
| High visibility case | From a distance, it's color makes it easy for Safety Professionals to verify that workers are protected. |
| 5 second delay shut-off protection | Portable O 2  detector  cannot be accidentally shut off since the on/off button must be depressed for five continuous seconds. |

performance:
1. Flexible convenient and versatile. It can save a lot of infrastructure and removal cost.
2. Reasonable compact space layout greatly reduces the the occupied space of the equipment in the field.
3. Crushing materials in working site immediately and moving with the mining surface of raw materials greatly reduce the material transportation cost.
4. The equipment chassis is high and the turning radius is small make it easy to travel on ordinary road and the rugged road.
5. It can use external power supply as well as high reliability diesel generator.
6. The technology for Crushing And Screening Equipment is mature structure is compact and performance is stable
