Teledyne T201 Ammonia Analyzer, Do not pressurize the Sample/Span/Zero port above ambient

1.0 T201 AMMONIA ANALYZER

This manual is to be used in conjunction with the T200 NOx Analyzer manual, p/n 06858 supplied with this instrument. It is important that you familiarize yourself with the workings of the NOx analyzer before proceeding with NH3 measurements.

The T201 ammonia analyzer consists of a modified T200 nitrogen oxide analyzer and an M501 NH3 ammonia converter. The analyzer measures the following individual gas concentrations: TNx (NH3 and NOx), NOx (NO and NO2) and NO in the sample gas.

The ammonia concentration is calculated by subtracting the NOX reading from the TNx measurement.

The nitrogen dioxide concentration is calculated by subtracting the NO reading from the NOx measurement.

	The instrument comes in three pneumatic configurations:
	 The T201 with External Calibrator Option (ECO) is shown in
	Figure 1-1.
	 The basic system is shown in Figure 1-2.
	 The T201 with Zero/Span valves is shown in Figure 1-3.
Note	For a T201 analyzer with Zero/Span option you must connect the umbilical
	cord P/N 02255 between the analyzer and the external M501 NH3 converter
	assembly.
	If the analyzer is purchased without the Zero/Span option then the zero and
	span calibration gases must be individually applied to the Sample port.
	Remember, the gases must be clean/dry and supplied at ambient pressure.
	CAUTION
	Do not pressurize the Sample/Span/Zero port above ambient
