2、 Product Introduction
Suitable for unmanned all-weather collection of pollutants such as fluoride, heavy metals, and particulate matter in the ambient air. Equipped with a PM2.5 cutter, it can achieve sampling of various particulate matter such as TSP, PM10, PM2.5, etc., while meeting multiple flow points such as 16.7L, 50L, 100L, etc., achieving multi use with one machine. It can be widely used in environmental monitoring, health and epidemic prevention, labor protection, scientific research institutions and other departments for various pollutant monitoring.

3、 Main features

1. Adopting imported brushless high load 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 20000 hours. It can overcome 20kPa resistance at flow rates of 50L/min and 100L/min.
2. By combining imported electronic flow meters with microcomputers, it has a high degree of intelligence and is easy to use.

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

4. The fluoride sampling head and TSP/PM10/PM2.5/PM1 sampling head are all made of aluminum alloy material, which has anti-static adsorption and has been verified by the Environmental and Health Related Product Safety Institute of the Chinese Center for Disease Control and Prevention.

5. 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.

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

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

8. 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.

9. 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.

10. The sampled data can be printed or exported from a USB drive, and the USB drive capacity can be automatically recognized.

11. Equipped with a dual membrane fluoride sampling head as standard, it meets the HJ955-2018 "Determination of Fluoride in Environmental Air - Membrane Sampling/Fluoride Ion Selective Electrode Method".
