Purpose:
Used for collecting particulate matter/microbial samples such as TSP/PM10/PM5/PM3.5/PM2.5/PM1, as well as aerosol and gas samples such as SVOC/iodine/fluoride/oil fume/metal dust (user optional cutter).
Main features:
1. Adopting mass flow sensors, microcontroller technology, and constant current sampling technology, the flow rate is stable and the sampling volume accuracy is high.
2. Powered by a brushless vacuum pump, it has a long lifespan and low noise.
3. Good load characteristics, able to overcome 25kPa resistance at a flow rate of 40L/min.
4. The range of sampling flow rate setting is wide, within the range of (15~42) L/min, the sampling flow rate can be set arbitrarily, which is convenient for users and expands the range of instrument use.
5. The working voltage range is wide, and it can work normally at AC (100~242) V.
6. The cutter and filter are connected by a locking device, which is easy to install and disassemble, and has good air path sealing.
7. Strong adaptability to the environment, able to work in an environment of (-30~50) ℃, and able to work in humid, rainy, foggy, weather, and corrosive gas environments in the ocean.
8. Good safety/anti-interference/low noise.
9. Small size, light weight, easy to transport, store, and carry
10. Digital setting, display, and calibration functions: able to digitally set sampling flow rate and sampling time; Automatically display sampling flow rate (operating conditions) and sampling volume (standard conditions); Capable of digitally calibrating sampling flow rate, time, temperature, and pressure.
11. Overload automatic protection function: When the sampler deviates from the set sampling flow rate by 10% for 5 consecutive minutes, the sampler will automatically stop for protection.
12. Data communication function: Using 232 serial port, data can be uploaded to the computer for processing.
13. Storage and query sampling data function: capable of recording 20 sets of sampling data for users to query.
