1. Description ZY6192 type wire and cable combustion halogen acid gas measuring device is used to determine the total halogen acid gas of low halogen and halogen-free flame retardant cable and to measure the acidity of the gas by measuring the PH value and conductivity. Its design conforms to GB/T17650.1-1998, GB/T17650.2-1998 and IEC60754.1-1998, IEC60754.2-1991 standards, and also meets GB/T19666-2005 "flame retardant" The provisions of Table 6 of the Standard and General Rules for Refractory Wires and Cables and the requirements of Articles 6.3.4 of GA306.1-2007, 6.3.4 of GA306.2-2007, 9.10 and 9.11 of UL2556-2007. The equipment is accurate in testing, reasonable in structure and simple in operation. It is convenient for wire and cable manufacturers, colleges and universities, commodity inspection departments and scientific research units. 2.
