          氧氣O2氣體檢測管159SA OXYGEN 2-24%,體外缺氧:主要是因為外部原因造成的缺氧。人處在一個缺少氧氣的環(huán)境里,如陰天氣壓低,高原地區(qū),環(huán)境污染地區(qū)以及寫字樓、商場、地下室等都容易造成體外缺氧。體內(nèi)缺氧:是指人體自身的原因,導致吸入氧氣的不足,與一些老年病、工作節(jié)奏快等原因有關(guān)。如呼吸系統(tǒng)疾?。夤苎?、哮喘);血液循環(huán)不好(各種心臟疾病,腦供血不足、腦梗、脈管炎、靜脈曲張等)。長期處于體內(nèi)缺氧狀態(tài),人體各個組織供氧不足,加速了身體的衰竭,甚至引發(fā)中風等意外,直接威脅到生命的安全。

          Carbon dioxide 〃5% 〃
          6.NOTE
          1)Coexistence of more than 5%of Carbon dioxide(CO2)gives higher reading and the reading from the scale
          should be corrected with the following correction table.
          2)The 59SA and SB tubes are necessary to heat the part of the temperature indicator until the indicator
          discolours from Red to Purple first. In case of 59SA , it is necessary to use direct flame such as a match
          or lighter to heat it up a non-hazardous area.59SB consists of a thin aluminum belt rolled on the indicator
          and chemical liquid in a small bottle. When the liquid is dropped on the aluminum fully, a chemical reaction
          occurs with generating smoke and temperature comes high. There, the 59SB is possible to use in a
          hazardous area.
