The Optris CTratio 2 color infrared thermometer is ideal for measuring high temperature metals, it's short measuring wavelength 5ms to 10s response time enable the CTratio to accurately measure very fast processes. It is generally unaffected by dust and steam, and can even maintain high accuracy through dirty observation windows. It can operate in temperatures up to 482°F without impacting measurements or requiring additional cooling.

A built in laser marks actual spot size at any distance. Adjustable signal processing features include 1 and 2 color mode, attenuation monitoring, alarm, peak hold, valley hold, average, and extended hold function with threshold and hysteresis.

The Optris Compact Connect temperature analysis software is available as a free download, and is necessary to document and analyze temperature measurement data. It is compatible with all netbooks, notebooks, and PC systems via Windows XP, Windows Vista, Windows 7 and 8.
