Notes
1. Specifications
IM 11M10A01-03E
This sampling unit is designed for the OX100 Series Oxygen Analyzers when they are
used where a sample gas contains a small amount of organic solvents (isopropyl alco-
hol), such as in reflow furnaces.
The sampling unit comprises two membrane filters to eliminate dust and mist, a suction
pump to draw a sample gas, an activated carbon filter to eliminate organic solvents, and
a flowmeter to monitor sample gas flow rates.
If repair is required, the is equipment will need to be returned to the factory. For repair
