According to the forecast of the Tibet Autonomous Region Meteorological Bureau, the spatial and temporal distribution of precipitation in Tibet from April to September this year is uneven, and the total amount is slightly less normal. In the Changdu area and Linzhi area in April, there were more normal localities in the Nagqu area and less in other areas. In the early summer (May to June), the Yajiang River has more precipitation, and other areas are normal or less. In the midsummer (7-8), the Yajiang River has less precipitation, and there are sunny and hot rain periods. The meteorological drought level is higher in some areas; the strong precipitation weather in Changdu area, the probability of geological disasters such as mountain floods and mudslides are relatively high. At the beginning of the rainy season, the Yajiang line was slightly earlier, the Qamdo area was slightly late, and other areas were normal. The temperature in the district was slightly higher from April to September.

1. The recent large-scale precipitation weather in Tibet is beneficial to the production of agriculture and animal husbandry. All regions must seize the favorable opportunity to carry out spring ploughing and preparation work. Due to the high intensity of precipitation in the eastern region and the thick snow in the mountains, it is necessary to pay attention to prevent snowmelt geological disasters.
2. According to the forecast of climate trends in flood season, most areas in midsummer have more sunny and less rainy weather, and the meteorological drought level is higher. Please strengthen farmland irrigation and forest fire prevention work.
3. There are short-term and strong precipitation weather processes in the eastern part of the midsummer. It is easy to cause geological disasters such as mudslides and landslides, which have adverse effects on agriculture, transportation, communications, etc., and invite relevant departments to strengthen prevention work.
Dissolved oxygen analyzer is mainly used to detect the oxygen content in solutions. It consists of a Dissolved Oxygen Controller and a Dissolved Oxygen Sensor. Real time feedback of data to the controller through sensor measurement.
Dissolved oxygen refers to oxygen molecules dissolved in water. It is one of the gases necessary for the survival and breathing of organisms in water bodies. The concentration of dissolved oxygen in water can affect the growth and health of aquatic organisms. The online dissolved oxygen analyzer can realize real-time continuous monitoring of the dissolved oxygen value of water quality.
The measurement principles of dissolved oxygen analyzers usually have the following types:
Polarography: An electrode is immersed in water to measure the dissolved oxygen content based on a change in current or potential generated by a redox reaction between the dissolved oxygen and the electrode.
Optical method: This method uses an optical dissolved oxygen sensor to measure the dissolved oxygen concentration. One common optical sensor is the oxygen sensor, which uses an oxygen-sensitive dye to detect the amount of dissolved oxygen in water. These sensors can measure using principles such as fluorescence or absorption spectroscopy.
Chemical methods: Chemical methods typically use reagents to measure dissolved oxygen levels. These reagents chemically react with dissolved oxygen to produce a measurable color change or electrical signal, allowing the concentration of dissolved oxygen to be determined.
Daruifuno's DUC2-DO dissolved oxygen analyzer is equipped with an optical dissolved oxygen sensor. The fluorescence method does not consume oxygen, does not require electrolyte, has a fast response and is convenient for measurement.
