1. Introduction to the instrument

The instrument is equipped with sensors such as rain sensor and rain gauge. Four different working modes can be set to collect mixed samples and segmented samples. The samples can be loaded into 8 different segments according to different segmentation rules. in the container. Automatic and continuous collection, preservation and monitoring of atmospheric precipitation and dustfall samples can be used for routine monitoring and scientific research requirements of atmospheric precipitation and dustfall by environmental protection, health, labor, safety supervision, military, scientific research, education and other departments.

2. Technical characteristics

1. Using two independent parallel intelligent rain sensors, it can automatically judge the precipitation situation and determine the working state of the instrument to prevent misoperations such as bird droppings, fog, and dew; it has the functions of collecting mixed samples and segmented samples. Equipped with an eight-segment converter, four different working modes can be set, and the samples can be loaded into 8 (optional 16 ) 800mL different containers according to different segmentation rules;

2. Using a famous refrigerator, the samples can be stored at (4 ± 1) ℃ in the ambient temperature (0 ~ 50) ℃ ;

3. 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;

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

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

6. Optional GSM module for remote wireless data acquisition and control.
