Key Features

  • A250+ and A450+ are highly accurate Focusable Pyrometers. They are useful in providing high performance of non contact temperature measurement in demanding industrial and R&D environments.
  • The parameters like Emissivity, Response time,Peak picker can be set via the Key pads on the back panel. The settings are displayed on the large colour video LCD (55.5 (W) x 47.9 (H) x 3.17 ((D). In measuring mode real time temperature and Emissivity is displayed. In Focusable Pyrometer with video module the real time colour video, measuring temperature and Emissivity is displayed on the LCD screen.
  • A250+ and A450+ have Focusable optics for optimal match of the instrument to various application requirements. The pyrometers are equipped with user selectable RS232/RS485 switchable interface.The Analog outputs provided are 0 to 20mA, 4 to 20mA, 0 to 10V.
  • A250+ and A450+ are single color options while A450C+ is a two color model. The pyrometers are switchable between Single and two color modes.
  • Data logging and remote parameterization can be performed through factory supplied PC softwawre “Infrasoft”. Laser targeting light, Through the lens sighting, Video output(optional) are available with this series.
