Halogen Acid Gas Emission Measurement Apparatus

Description:

This apparatus measures the pH value, acidity, and conductivity of gases emitted during the combustion of materials from cables or optical cables. It is used to determine the total halogen acid gas content in low-halogen and halogen-free flame-retardant cables and to assess gas acidity through pH and conductivity measurements.
