ZR-3713 Dual VOCs Sampler Introduction
ZR-3713 dual-channel VOCs sampler adopts adsorption tube sampling method and other solid-phase adsorption methods, which can collect volatile organic compounds such as benzene series, aldehydes and ketones, halogenated hydrocarbons in ambient air, and simultaneously with flue gas. The processor can also be used to determine the volatile organic compounds in the fixed source exhaust gas.
