1. Introduction to the instrument

This instrument is equipped with a rain sensor and a snow melting rain and snow gauge with a heating device, which can collect the "mixed sample" samples that meet the national standard HJ/T 174-2005 "Technical Requirements and Testing Methods for Rain Automatic Samplers". When collecting mixed samples, the rainwater collected from one day such as 9:00 ( according to the set time) to 9:00 the next day ( according to the set time) can be stored in a container, and the rainwater collected at 9:00 (the set time) can be stored in a container . ) before and after the rainwater into two different containers.” (refrigerator not included). It can be specially developed for collecting rain and snow in northern regions, and can meet the routine testing and scientific research requirements of environmental protection, meteorology, health, labor, security inspection, military, scientific research, education and other departments for atmospheric rainfall, snowfall, and dustfall.

2. Technical characteristics

1. Adopt two independent parallel rain sensors with written heating, which can automatically judge the precipitation situation and determine the working state of the instrument, preventing the misoperation of bird droppings, fog, dew, etc.;

2. Equipped with a snow-melting rain and snow meter with a heating device as standard, and a snow-melting water harvesting funnel with a heating device, a thermostatic conversion valve and a thermostatic pipeline in the body;

3. The body is equipped with two 10L precipitation sampling buckets;

4. 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;

5. It has the function of dust collection and preservation.
