PRINTED DOCUMENTS ARE UNCONTROLLED
1. OVERVIEW
The model M200EU is a close derivative of the Model 200E NOx Analyzer. The main
differences are as follows.
The M200EU is more sensitive at low NOx
levels than a standard 200E. The
instrument has a user selectable full scale range of 0-5 PPB to 0-2000 PPB of
NOx.
The reaction cell is gold plated. In addition, there is a pre-reactor, which allows
the measurements of any hydrocarbon interferents in the sample stream.
The sample flow is about 1000 cc/min.
The M200EU is equipped with a high performance pump, capable of producing a
reaction cell pressure of less than 5 Inch Hg absolute.
In addition to the contents of this M200EU Addendum, you must use the M200E manual.
CAUTION!
The following procedures apply only to the External Zero Air Scrubber and NOT to the inline
exhaust scrubber cartridge that is part of the pump pack assembly.
NOTE
The M200EU has equivalency approval, and may be used
for EPA monitoring.
