Appendix 1. Sampling Unit
K9424GA Sampling Unit for OX100/102
This sampling unit is designed for the OX100 Series Oxygen Analyzers and is used where a
sample gas contains a small amount of organic solvent (e.g. isopropyl alcohol), 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.
NOTE
If repair is required, the is equipment will need to be retuned to the factory. For repair or
maintenance, contact your Yokogawa representative.
