OPT-PI400 / OPT-PI450

Infrared camera





The infrared cameras Optris PI 400 and PI 450 are the smallest thermographic cameras in their class. Equipped with a measurement speed of 80 Hz and an optical resolution of 382 x 288 pixels they provide real-time thermographic images in high speed.

The PI 400/450 standard model offers a temperature range of -20°C... 900°C. The Optris PI Connect software, included in the package, offers video and snapshot recordings, extensive analyses (offline, online) and is equipped with an integrated line scan camera function. PI 400/PI 450 can be delivered with three different optics.

PI 400/PI 450 can be delivered with three different optics. Due to its thermal sensitivity of 40 mK, PI 450 is specifically suited for detection of slightest temperature differences, making it indispensable in quality control of products and in medical prevention.

Differences between PI 400 and PI 450:

  • Thermal sensitivity (NETD) depending on the optics:  0.08K-0.1K in PI 400 and 0.04K-0.06K in PI 450.
  • Higher ambient temperature and storage temperature in PI 450.
  • Additional temperature range only available in PI 400.
