General Pyrometer A series

A Series

Standard Industrial Models
A series pyrometers are specially designed IR Pyrometers for non-contact temperature measurement in demanding industrial environments. The Pyrometers are highly accurate and compact by nature with stainless steel housing to provide high operational safety for harsh industrial environments.


Key Features

  • A250 and A450 are single colour options while A250C & A450C are two colour models. The pyrometers are switchable between Single- and Two-colour modes.
  • A250 FO-PL & A450 FO-PL are highly accurate digital Fibre Optic industrial IR Pyrometers, for non-contact temperature measurement. The Fibre Optic Pyrometers are widely used in high ambient temperature applications without cooling and the processes involved in electromagnetic interferences.
  • Laser or Through the Lens view finder sighting options.
  • Analog output options are available like 0…20mA, 4…20mA and 0…10V.
  • A150 is a specially designed model from the 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 75°C as the emissivity of un-oxidized metal surfaces is higher at shorter wavelengths.
  • Bluetooth V2.0 and RS-232/ RS-485 Serial interface.
  • User-friendly Infrasoft PC software for communication.
