Model T200U NOy Option Manual Addendum
07303E DCN7996 7
1.0 INTRODUCTION
The T200U NOy analyzer consists of an external thermal converter designed to
support a NOx analyzer by converting multiple, unstable compounds grouped
under the name NOy . The converter is mounted externally at the sample inlet to
minimize flow time between sample in and converter, thereby optimizing
measurement accuracy. The sample is pulled through the converter box by the 501
NOy pump pack.
The 501 NOy pump pack contains a temperature control unit for the converter and
an internal pump. The pump pack pulls ambient air into the converter box via the
sample port; the sample port’s cross-fitting splits the sample between two paths:
one bypasses the heated converter and flows directly into the pump pack via the
tubing for NO, while the other path flows through the heated converter assembly
first, and then flows into the pump pack via the tubing for the converted NOy. From
the pump pack the separate samples flow to the analyzer.
This manual addendum is to be used in conjunction with two additional documents
with operation instructions:
•
T200 operation manual (part number 06858)
• T200U addendum (part number 06861).
It is recommended that you read/familiarize yourself with all sets of instructions in
order to use the analyzer and converter correctly.
