Description:
The J.U.M. Engineering HFID Model VE7 is very
rugged and versatile 19" rack mount heated total hydrocarbon
analyzer for high accuracy, sensitivity and stability.
The Model VE7 uses a hydrogen flame ionization
detector (FID) in a heated oven to prevent the loss of high molecular
weight hydrocarbons and to provide reliable performance in the
analysis of trace level of contaminants in high purity gases,
air and other gases.
The permanent heated sample filter is cleaned
by backpurging and has a replaceable stainless steel mesh filter
disc. A rear adaptor-system allows cold-spot free coupling of
a heated sample line inside the heated oven without the need
of special tools.
