Features:

1. The dust precipitation automatic sampler host stainless steel, coating, corrosion sample barrels containing pollution shield, comb sensor. High sensitivity, strong anti-jamming capability, refrigeration (3 ~ 5 ℃) to preserve the samples.

2. The sampler precipitation automatically when open, shut down automatically at the end of the precipitation, continuous automatic sampling.

3. Can collect samples of rain and snow, also can clear dry dust samples.

4. Precipitation dust inside the automatic sampler has the function of intelligent process control system and data memory, precipitation can connect microcomputer number display and print management functions.

5. The dust precipitation automatic sampler is special computer software, the operation is simple. Microcomputer and sampler for remote communication, in order to obtain the sampler precipitation records, computer operating system: Windows

6. When using a comb or rotation sensors, can distinguish precipitation intensity, the user can set open time, but in addition to the interference effectively.

7. Precipitation over closed dust cover time can be set in a user.

8. Environmental adaptation ability strong, can be in to 40 ℃ to 50 ℃ temperature environment and 9 levels under the wind environment, using multiple lightning-proof measures, to ensure that work 24 hours a day.

9 with standard rain gauge, sensing method: tilting or siphon type.

10. Dust precipitation automatic sampler to satisfy the People's Republic of China environmental protection industry standards (HJ/T174-2005) the rainfall automatic sampler technical requirements and test methods of technical requirements.
