一、检定注意事项1.气体标准物质的选择检定所选用的标准气体类型应与被检报警器所测气体类型一致,因为报警器在出厂设置时,大多已根据用户要求用所测气体进行示值标定,因此检定前,应询问使用厂家需要测定的气体类型,如燃气公司的天然气主要成分为甲烷、石化厂的石油液化气主要成分为丙烷、煤气锅炉车间的煤制气主要成分为氢气和一氧化碳等。如实在没有相同种类的标准气体,在用不同的标准气体检定后,需根据具体厂家的气体
First, the verification note 1. Gas standard material selection test The selection of the standard gas type should be detected with the alarm gas measured the same type of gas, because the alarm at the factory settings, most of the gas has been measured according to user requirements Therefore, before testing, the type of gas to be measured by the manufacturer should be inquired. For example, the main component of the natural gas of the gas company is methane. The main component of liquefied petroleum gas from the petrochemical plant is propane. The main components of coal gas in the gas boiler plant are hydrogen and Carbon monoxide and so on. As a matter of fact, there is no standard gas of the same type, after using a different standard gas test, according to the specific manufacturers of gas
