　　2、 Application of JH-120F particle sampler

　　The application of filter membrane weight method to collect particulate matter in the atmosphere is suitable for all-weather particulate matter sampling. It is equipped with a PM2.5 cutter to collect various particulate matter such as TSP, PM10, PM5, PM2.5, etc. It can be widely used in environmental monitoring, health and epidemic prevention, labor protection, scientific research institutions and other departments for particle concentration monitoring.

　　3、 Performance characteristics of JH-120F particle sampler

　　1. Small in size, light in weight, easy to carry, capable of collecting various particulate matter and automatically measuring atmospheric pressure.

　　2. By combining imported electronic flow meters with microcomputers, it has a high degree of intelligence and is easy to use.

　　3. Adopting imported wide temperature OLED display screen, it can work in warm environment, with good human-machine interface and interactive operation.

　　4. Adopting a brushless motor vacuum pump, it has high reliability for long-term continuous operation, low noise, long service life, and a fault free operation time of more than 10000 hours.

　　5. Real time clock, with various sampling methods such as timed sampling, interval sampling, multiple sampling, and cyclic sampling, available for users to choose from.

　　6. The rechargeable battery of the instrument is used to save data during AC power outages. It automatically restores sampling during AC power outages, deducts the power outage time during the sampling process, and allows users to query the power outage time.

　　7. Automatic fault protection function, if the set flow rate is not reached within the specified time, automatic shutdown protection will be implemented.

　　8. Tripod cloud desktop design for easy operation.

　　9. Optional AC/DC dual-purpose host and ZD-24 DC power box, capable of sampling in situations without AC power.

　　10. Automatic flow control, embedded software design, automatic calculation of sampling volume, automatic memory of sampling data, priority use for next boot, achieving one click sampling.

　　11. Collecting TSP, PM10, PM5, and PM2.5 in one, the cutters are made of aluminum alloy material with anti-static adsorption.

　　12. Display multiple parameters including standard time, delay time, sampling time, sampling frequency, cumulative flow rate, instantaneous flow rate, atmospheric pressure, etc.

　　13. Users can calibrate the instrument through the keyboard, and maintenance requires a password to enter, ensuring the security of instrument data and preventing easy modification errors. It also provides the function of restoring factory settings.

　　14. Silencing device, achieving sound operation with a noise level of less than 50 dB (A).
