Low Concentration Version DH6-LC
For measurement of very low concentration ozone, e.g. in humid vent gas behind an ozone de-
struct, the model DH6-LC is available. It has an inner PTFE lining, and a particle filter installed
at its outlet, assuring that the full length of tubing leading the sample gas to the ozone monitor is
protected against contamination by any particles contained in the sample gas.
The fitting at the outlet of the sample gas filter is accepting 1/4" (or 4x6 mm) FEP or PFA tub-
ing for direct connection to an OZONE MONITOR BMT 932.
