TH8145 Halogen acid gas release measuring device
Overview:
It is used to determine the total amount of halogen acid gas in low-halogen and halogen-free flame-retardant cables and to measure the acidity of the gas by measuring the PH value and conductivity.
Comply with standards: GB/T17650.1-1998, GB/T17650.2-1998 and IEC60754-1:1994, IEC60754-2:1991 standards; at the same time meet the GB/T19666-2005 "Flame-retardant and fire-resistant wires and cables" standard Table 6 regulations and GA306.1-2007 Article 6.3.4, GA306.2-2007 Article 6.3.4, UL2556-2007 Article 9.10 and 9.11 requirements.
