Working mode: manual sampling; Timing sampling; Quantitative sampling; Interval sampling;

Data display output: Chinese display, including real-time flow, cumulative sampling volume (standard condition volume), cumulative sampling time, equipment alarm status (including but not limited to: voltage, overload, overcurrent, current, frequency converter, etc.), equipment working status and sensor measurement value;

Data query: historical sampling records and alarm records can be queried, and data can be printed;

Data transmission: the sampler data can be transmitted to the remote server or computer remotely;

Remote control: the sampler can be configured and switched on and off through a remote computer;

Setting function: the system provides the user with the function of setting and querying various parameters related to sampling;

Maximum cumulative flow of sampling: 9 M3

Remote fault alarm function;

Wireless communication function;

Fault alarm function: it can automatically detect filter membrane blocking, flow rate lower than the preset value, pump temperature too high, power supply abnormality, motor overload and other alarms, and take automatic power off or shutdown to ensure the safety of the whole system;

With RS-232 serial port, it can expand wireless network, broadband, optical fiber and other wired networks;

It is convenient and quick to replace the filter paper, and the filter paper will not be affected by the weather (especially the wind).
A standard interface is set at the entrance, which can be connected to the flow calibration interface;

The whole pipeline has good air tightness;

The sampling system meets long-term and stable operation under all-weather conditions in the field;

When the instantaneous flow is lower than the set value, pause sampling (without interrupting the sampling process) and prompt the user to change the filter paper;

When the voltage is abnormal and the deviation is ± 10, the sampling is normal;
