GAS SAMPLING CHAMBER SYSTEM

摘要

PURPOSE: A gas collection chamber system is provided to collect pollutant gas after sealing the entire area of a substance generating the pollutant gas, for accurately measuring the concentration of the pollutant gas. CONSTITUTION: A gas collection chamber system comprises a chamber(10), an airflow volume regulator(20), a gas transfer pipe(30), a gas mixing unit(40), a gas controlling valve(50), and an inhalation pump(60). The chamber includes an outer air inhalation hole(11), and an exhausting hole(12) on the upper side. The airflow volume regulator includes an outlet(23), and an airflow volume controlling fan for discharging polluted gas inhaled through an inlet(22). The gas transfer pipe connects the exhausting hole of the chamber and the outlet of the airflow volume regulator.
