HBJ-3A acid rain automatic sampler

HBJ-3ATechnical indicators of precipitation sampler

function

1. Adopting comb shaped sensors, with high sensitivity and strong anti-interference ability. Equipped with a heating device to prevent interference from fog and dew; Can melt snow for snow harvesting; After the precipitation ends, steam dry the rain and snow, and promptly close the lid.

2. Automatically open the dewatering bucket and seal the dustbin during precipitation; Automatically close the precipitation bucket and open the dust bucket when the precipitation ends; Continuous automatic sampling.

3. The mechanical system adopts a double barrel four-bar linkage structure, which is reliable in action. The sampling barrel is well sealed and pollution-free, making sampling convenient.

4. The control system is stable and reliable, with strong anti-interference ability and no misoperation.

5. Rain and snow samples can be collected on rainy and snowy days, and dry dust samples can be collected on sunny days. And samples can be stored in a refrigerator at 1 ℃ to 5 ℃ according to user requirements.

6. Strong adaptability to the environment, it can be used in environments with temperatures ranging from -40 ℃ to 50 ℃ and wind speeds below level 9.

7. The sampler has intelligent program control function and data memory system inside, which can be connected to a microcomputer to achieve functions such as precipitation data display and printing management.

8. The microcomputer software is easy to operate and can be learned and used at the same time.

9. There is no limit to the amount of data recorded by indoor microcomputers.

10. Automatically record every precipitation record within a month (with the start and end time and precipitation amount as one record), and read the previous month's precipitation records at any time indoors through a microcomputer, and generate a report for printing and summarizing

11. The sampler has a rain gauge inside and can also be equipped with a standard rain gauge.

12. The time for closing the dust cover after precipitation can be set by the user.

13. The sampler can communicate wirelessly with a microcomputer at a distance of 0-40km to obtain precipitation records from the sampler.
