1. Preparation work: inspection+arrangement

confirmExplosion proof atmospheric samplerThe appearance is undamaged and the explosion-proof markings are clear (meeting the requirements of the explosion-proof level);

Check that the battery is fully charged (or connected to a compliant power source), the filter membrane and sampling tube are installed properly and unobstructed;

Choose a sampling area with good ventilation and no open flames, and avoid flammable and explosive environments.

2. Parameter settings: Simply adjust 3 items in place

After turning on, press the "Mode" button to select the sampling type (such as "fixed-point sampling" or "continuous sampling");

Set the sampling flow rate (usually 0.1-1L/min, adjusted according to the detection standard) and sampling time through the numerical keys;

After confirming that the parameters are correct, press the "Confirm" button to save.

3. Start sampling: one click operation

Align the sampling tube inlet with the sampling direction (away from the pollution source discharge outlet directly below);

Press the "Start" button, the sampler starts working, and observe that the display screen data is stable (flow and time count normally).

4. Sampling: Simple inspection

No need for dedicated personnel to be on duty, check every 10-15 minutes: the sampler has no abnormal noise, no air leakage, and no parameter drift;

If there is a flow fluctuation, promptly check whether the sampling tube is blocked, clean it, and restart it.

5. Ending work: Closing and recording

After the sampling time is up, the sampler automatically stops and the power is cut off by pressing the "shutdown" button;

Remove the filter membrane and sampling tube, seal and store them, and mark them properly (sampling time, location, parameters);

Clean the air inlet of the sampler and store it in a dry, ventilated, and explosion-proof area.
