Performance Characteristics

1. It has small size, light weight, low noise, high degree of intelligence, stable flow rate, reliable operation, and integrates the collection of atmospheric and particulate matter.

2. The microcomputer simultaneously controls three sets of sampling systems for atmospheric and particulate matter, with multiple sampling methods including simultaneous sampling, individual sampling, multiple sampling, alternate day sampling, and cyclic sampling.

3. Adopting imported wide temperature OLED display screen, with a good human-machine interface and vivid graphics, easy operation, and Chinese graphic display, it can work in ultra-low temperature environments.

4. The dual channel atmospheric and particulate matter three-way sampling systems both use imported DC brushless vacuum pumps, with a fault free usage time of over 10000 hours.

5. Users can choose to equip a dual-purpose AC/DC host with a ZD-24 DC power supply box, which can sample in situations without AC power.

6. Using imported sensors, the sampling flow accuracy is high and the stability is good. It can measure atmospheric pressure and temperature, and automatically convert states based on pressure and temperature
