Sample Outlet, Rc1/4
Activated
Carbon Filter
IM 11M10A01-03E
The sampling unit comprises membrane filters, suction pump, flowmeter and activated
carbon filter to absorb organic solvents. When a sample gas contains organic solvents,
use this sampling unit to filter out such solvents. The expected life of the activated
carbon filter is approximately 50 hours when a sample gas contains 500 ppm of isopro-
pyl alcohol and flows at 500 ml/min.
Used eight hours a day, suction pump life will be approximately one year.
