一、检定时的注意事项1.注意仪器的检测范围可燃气体的浓度显示值取决于可燃气体与空气中的氧气进行催化燃烧过程中产生的热量。要注意空气流通,比如在封闭室内要开窗通风,对一个封闭区域(如储罐、容器等),由于其氧含量低于10%,所以不能检测,且不能检测以惰性气体为背景的气体中可燃气体的浓度。不得使用高浓度可燃气体测试判定报警线路是否正常。高浓度的可燃气体会产生很大的电桥电压差,且产生大量热量,降低了报警器中催化剂的含量,
First, the verification of the Notes 1. Note that the detection range of the instrument shows the value of combustible gas concentration depends on the combustible gas and oxygen in the air during the catalytic combustion heat generated. Pay attention to air circulation, such as to open the window ventilation in a closed room, to a closed area (such as storage tanks, containers, etc.) can not detect due to its oxygen content less than 10%, and can not detect gas with inert gas background In combustible gas concentration. Do not use high concentrations of flammable gas test to determine the alarm line is normal. High concentration of combustible gas will have a great bridge voltage difference, and produce a lot of heat, reducing the catalyst content of the alarm,
