Introduction

The Model RGA (see part numbers in the Parts List on page 1) is a Multi-Gas IR analyzer. It measures Carbon Monoxide (CO), Carbon Dioxide (CO₂) and Natural Gas (CH₄) typically found in an endothermic atmosphere.  The measurement of these gases, combined with furnace temperature information, allows the RGA to calculate the percent Carbon (%C) of the measured gas. A Hydrogen (H₂) sensor can also be incorporated as an option to provide a more complete picture of the measured gas.

 

For nitriding and ferritic nitrocarburizing (FNC) applications, the RGA can calculate carburizing potential (K_C) and nitriding potential (K_N).

 

Finally, the RGA can be configured for compatibility with environments containing ammonia (NH₃) gas. NH₃ compatibility must be specifically requested when the RGA is ordered.

 

NOTE: Calculation of Kc may have inaccuracies in the presence of ammonia.

 

IMPORTANT!   Do not use a RGA for gas analysis with NH3-containing gas if the RGA has not been configured with NH3 compatibility. Any use of a non-NH3 compatible RGA with NH3-containing gas will void the product warranty.
