A long-wavelength thermal imager providing a full temperature measurement range of -20 to 1000 °C (-4 to 1832 °F) in three ranges with a choice of different optics and lenses.
  • Overview +

    With increasing demand for improved product quality and efficiency, energy saving, predictive maintenance and emission reduction, thermal imaging cameras and systems play an important role in modern and industrial processing. 

    The new LWIR-640 long-wavelength thermal imagers build on more than 20 years of thermal imaging experience, expanding the market-leading range of AMETEK Land temperature measurement solutions. They offer a full temperature measurement range of -20 to 1000 °C (-4 to 1832 °F) in three ranges with a choice of different optics and lenses.

    An integrated webserver with multiple I/O options enables the camera to be used autonomously or easily integrated into new or existing process control systems. The webserver provides easy camera access, control and setup, using a standard browser.

    The LWIR-640 measures and streams live true-temperature images at up to 60 frames per second, providing high-precision temperature measurements and thermal profiles to continuously control, document, and visualise industrial processes.
