Q/2013LDZ 006-2015 "Atmospheric Comprehensive Sampler"

Technical features:

1. Can collect gas pollutants and TSP separately or simultaneously, with optional PM10/PM5/PM2.5 sampling probes;

2. Aluminum alloy particle sampling head effectively eliminates electrostatic adsorption;

3. Efficient and low-noise brushless fan;

4. OLED screen display, Chinese menu operation, wide temperature operation;

5. The atmospheric part adopts dual constant current sampling, with dual Japanese diaphragm pumps controlled separately;

6. The motor has intelligent automatic protection function. If the particulate matter sampling still does not reach the set flow rate within 35 seconds and the pressure is less than -9.0KPa, the sampling will automatically stop and wait for 30 minutes before starting again;

Automatic memory of 7 sampled data, providing 80 sets of data (expandable) for users to query and print; Equipped with a real-time clock, supporting timed and interval sampling settings;

8. Power down protection data, automatic recovery of sampling upon incoming call; Overload automatic protection function;

9. Directly measure atmospheric pressure and automatically participate in standard condition volume calculation;

10. One click sampling with user-friendly design, no need to reset parameters when restarting;

11. The heater is located inside the main unit and comes with an insulation cover. It has a light shielding function and can collect gas in low-temperature environments;

12. Equipped with a sampling gas path anti backflow device and capable of effectively achieving dehumidification protection function;

13. Password protection function ensures secure operation;

14. USB drive support.
