IR pyrometers from the A series family are highly accurate, compact and economic non-contact temperature measuring models. These are particularly useful for high temperature applications in wide temperature ranges from 250°C to 3000°C.


AST A Series Pyrometers

  • Pyrometers are available in Single Color and Two Color options. Almost 90% application can be solved through Single Color pyrometers. A two color pyrometer is recommended for applications involving changes in emissivity, surface finish, or energy-absorbing contaminants in surroundings such as smoke, water vapor, and dust.

  • A250 and A450 are single color options while A450C is a two color model. The pyrometers are switchable between Single and Two color modes. 
  • A150 is specially designed model from A series which operates at the near end of the IR spectrum and is thus an excellent choice for measurement of ferrous and non ferrous metals above 150°C as the emissivity of un-oxidized metal surfaces is higher at shorter wavelengths.
  • The A Series pyrometers have fast response time within milliseconds which ensures very quick temperature measurement required in fast heating processes.
