1. Introduction to the instrument

The instrument is equipped with sensors such as a rain ( snow ) sensor and a snowmelt meter. Four different working modes can be set to collect mixed samples and segmented samples. The samples can be loaded into different segments according to different segmentation rules. into 8 containers. Automatic and continuous collection, preservation and monitoring of atmospheric precipitation samples, and collection of dust fall samples, can be used for routine monitoring and scientific research requirements of atmospheric rainfall, snow and dust fall by environmental protection, health, labor, safety supervision, military, scientific research, education and other departments, especially suitable for northern area.

2. Technical characteristics

1. Two independent parallel intelligent rain (snow) sensors are used, which can automatically judge the precipitation and determine the working state of the device to prevent bird droppings, fog, dew and other misoperations;

2. Equipped with rain and snow meter, electric heating method, and automatic heating control by thermostat. The automatic measurement of precipitation can be performed in parallel and in parallel with the rainfall (snow) sampler;

3. Heated rain (snow) sampling funnel, which can carry out all-weather environmental sampling of rain (snow);

4. It has the functions of collecting mixed samples and segmented samples. Equipped with a heated eight - segment converter, which can set four different working modes, and load the samples into eight 800mL containers according to different segmentation rules;

5. The famous brand refrigerator is adopted, and the samples can be refrigerated at (4 ± 1) ℃ within the ambient temperature (0 ~ 50) ℃ ;

6. With RS232 interface, it is convenient for data dumping;

7. The switch cover adopts a double-arm four-link structure, with stable action and flexible sealing to ensure that the samples in the sampling barrel are free of contamination;

8. It has the function of dust collection and storage;

9. Storage and query of huge 8000 rainfall event data, the local data can be stored for more than 10 years;

10. With instrument fault self-check, power-down data protection and clock function.
