These rules apply also to your calibrator’s internal plumbing. It is highly
recommended that you use a M702SS calibrator in conjunction with the M201E.
The calibrator has stainless steel plumbing throughout. The M700 calibrator
contains Teflon tubing and internal MFC’s that can be affected by the ammonia
gas, therefore, the M700 calibrator is not recommend for use with the M201E
analyzer. It is important to keep the sampling system well maintained.
1.3 SAMPLE FILTRATION
The instrument can be provided with an optional stainless steel sample filter P/N
05571. For minimum response time operation, the instrument should be supplied
with clean sample gas at ambient pressure.
An additional filter resides in the M201E pneumatic pathway. The filter is a
¼” diameter stainless steel sintered filter used to protect the reaction cell flow
control orifice from plugging. This filter will plug rapidly if contaminated sample
gas is not filtered before entering the analyzer.
NOTE: In situations where the sample gas is known to be contaminated with
particulate material it is advisably to add extra filtration. However, it must be
noted that the response time is directly extended through filter additions.
