Water is known as the source of life. As long as it is a living thing on earth, it needs its pillars, cherish every source of life, and save water from me. Water can not only support the living organisms, but also the development of environmental testing equipment industry. The operation of the constant temperature and humidity test chamber also has certain requirements for the water source. Let us know below!
Water is divided into pure water, distilled water and mineral water. The water in daily life can be divided into soft water and hard water. The water with more soluble calcium, magnesium and iron salts is called hard water.
Pure water refers to H2O without impurities, referred to as pure water or pure water. It is pure, clean, and contains no impurities or bacteria. For example, organic pollutants, inorganic salts, any additives and various impurities are in line with life. The water standard for drinking water is raw water.
Distilled water is water that distills and condenses water. Steamed twice is called steamed water, and three times is called three distilled water. Low-oxygen water, potassium permanganate and acid industrial distilled water is obtained by distilled water, so distilled water is the best standard for water in constant temperature and humidity chamber!
Mineral water is naturally discharged from the depths of the underground or artificially exposed, uncontaminated underground mineral water; contains a certain amount of mineral salts, trace elements or carbon dioxide gas; under normal circumstances, its chemical composition, flow, Dynamics such as water temperature are relatively stable within the range of natural fluctuations.
The constant temperature and humidity test chamber has strict requirements for water. Generally, it uses pure water, distilled water and deionized water. The impurities in tap water are absolutely unusable.
