JH-1000 high flow particulate matter sampler

1、 Product Overview

The JH-1000 high flow particulate sampler is an instrument that uses the filter membrane weight method to collect samples of total suspended particulate matter (TSP), inhalable particulate matter (PM10), and fine particulate matter (PM2.5) in the atmosphere. It can be widely used in environmental monitoring, health and epidemic prevention, labor protection, scientific research institutions, and other departments for particle concentration monitoring.

Execution standard for JH-1000 high flow particulate matter sampler: JJG943-2011 "Total Suspended Particulate Matter Sampler"; HJ/T374-2007 Technical Requirements and Testing Methods for Total Suspended Particle Samplers.

2、 Performance characteristics

1. Adopting a wide temperature OLED display screen and a user-friendly interface with Chinese menus and vivid graphics, it eliminates the hassle of adjusting contrast and can work in low temperature environments.

2. The flow control adopts high-precision sensors with good flow stability and high sampling accuracy. It automatically detects the sampled flow rate, controls constant current sampling, and compensates for flow fluctuations caused by voltage and resistance changes.

3. Automatically record the cumulative flow rate and time during the sampling process, and convert the standard volume based on air pressure and temperature. Real time clock, with multiple sampling methods such as timed sampling, interval sampling, multiple sampling, and cyclic sampling.

4. Equipped with a rechargeable battery, it can store data during AC power outages, automatically restore sampling during AC incoming calls, deduct the power outage time during the sampling process, and allow users to query the power outage time.

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

6. Optional PM10 cutter for sampling inhalable particulate matter, optional PM2.5 cutter for sampling fine particulate matter, both cutters are made of aluminum alloy material with anti-static adsorption.

7. Automatically save the last user set parameters, and use them automatically the next time the device is turned on, achieving one click sampling. It can store 10000 sets of data, making it convenient for users to query.

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

9. Users can calibrate the instrument through a waterproof 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.

10. The rainproof design is suitable for any environment, and the flip structure can be folded for easy transportation.
