Bw-sa6200h portable large flow aerosol sampler is suitable for indoor and outdoor collection of various types of radioactive aerosol samples. Small size, light weight and large flow. The design of the suitcase is easy to carry. No special equipment is required to support the installation. The built-in high-capacity lithium battery can be used for work sampling at any time and place, mainly to monitor the radionuclide activity concentration suspended in particulate solid or liquid in the air. It is widely used in industry, agriculture, government and experimental research, chemical and radioactive analysis, and various other types of research, quality control and testing applications.

The fan with light weight, large flow and long service life is adopted to meet the large sampling flow and carry out the overall lightweight design;

The instrument has the function of interval (reservation) sampling;

Bluetooth wireless printing function;

Remote fault alarm function;

Wireless communication function;

Beidou transmission control function.

Support touch screen control;

The equipment can automatically scan the barcode identification of filter paper and manually input the identification number of filter paper;

Large capacity data storage, which can store more than 100000 groups of data;

It can display instantaneous and historical flow fluctuation curves;

It has the power-off memory function. After power-off, the incoming call can be recovered, the sampling can be continued, and the power-off and power-on time can be stored.

The instrument has a built-in electronic tag.

The instrument has built-in electronic gyroscope, dumping alarm and shutdown protection.

The instrument has an electronic manual, which can be obtained by one key scanning QR code on site.

The instrument has one key calibration function.

Built in lithium battery, which can meet relevant functions such as instrument query, printing and export.

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

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;
