Rainfall is one of the important parameters of meteorological elements, and precipitation is a phenomenon in nature. It can both benefit human beings and bring disaster to human beings. Therefore, accurately measuring precipitation intensity and precipitation has always been an important issue faced by various meteorological measurement units across the country. Rainfall is also an important parameter for meteorological elements observed by the meteorological department. In recent years, there have been certain developments in the detection of wind speed, temperature and humidity in the environment. They all have their own corresponding detection instruments. The wind speed monitoring is a wind direction anemometer, and the temperature and humidity monitoring is a temperature and humidity monitor. Rainfall monitoring can't fall behind, and rainfall measuring instruments directly rely on rainfall recorders. This is a professional measuring rainfall monitoring instrument, which is widely accepted by various regions.
Regular maintenance is required during the use of the rain gauge to ensure accurate measurement results and to extend the life of the instrument. The following procedures can be used for maintenance in the market:
1. Regularly observe the horizontal bubble (unscrew the outer nut and open the cover to see it on the chassis). If the horizontal bubble is not in the center circle, use a small wrench to adjust the horizontal screw. When adjusting, do not use excessive force to prevent the chassis foot from breaking. .
2. Regularly check the cleanliness of the water container, such as dust, leaves, insects, etc. The mesh cover in the water container can be cleaned by loosening the lower fixing nut.
3. The internal measurement of the instrument should also be regularly cleaned, but in the process of cleaning, be careful to prevent internal damage.
Rainfall recorder rainfall range: 0.1 ~ 4mm / min, rainfall accuracy: ± 0.4mm, resolution: 0.1mm. Meet the measurement requirements of most areas.

The compostable waste bags are made of fully biodegradable compostable material. It is non-traditional plastic material and does not contain any harmful substances. It can be completely biodegraded under composting conditions for 90 days. After use, the product can be composted together with the packaged materials (kitchen waste, garbage, fallen leaves, etc.). The compostable bags can be decomposed into CO2 and water by bacteria in the composting environment, and the bacteria die after the end of the degradation process and become organic fertilizer.
