Metal Heat Treatment

Hitech gas analysers are suitable for most types of atmospheres used in the metal heat treatment processes.


Some examples include:

  • Inert gas (nitrogen/argon) - Typically requiring the monitoring of low levels (ppm) of oxygen.
  • Endo gas - Typically used to generate a reducing atmosphere where the oxygen content is measured in fractions of an atmosphere partial pressure or oxygen potential.
  • Dissociated Ammonia - For high hydrogen content atmospheres to protect easily oxidised materials or to nitride them. For the hydrogen content any of the K (thermal conductivity) analysers - K1550, K6050 etc. These can be calibrated in percentage hydrogen or percentage ammonia dissociation.
  • Hydrogen bearing atmospheres (HNx) - Typically used to generate more highly reducing atmospheres such as are used for stainless steel, galvanised sheet etc. For the oxygen content (or dewpoint) any zirconia based oxygen analyser with a reducing atmosphere sensor and software e.g. Z110, Z1110, Z4010, Z210
