The Teflon-membrane particulate filter assembly, P/N 1830-0055 requires replacing this filter’s membrane, P/N
0235-1072 every 30 days.
* Hydrogen Bromide and Hydrogen Iodide are very water soluble. A high relative humidity (RH) will cause
sample loss due to absorption onto the sample lines. For these gases, use the table below as a guide to
determine the maximum sample length.

Note:
When monitoring for gases using low-level calibrations, additional sample line restrictions may apply. Consult
Honeywell Analytics.
