CSmicro LT Miniature Infrared Pyrometer

The CSmicro series of pyrometers are an evolution of the CS, with a miniature sensing head which is one of the smallest in the world measuring just 14mm OD x 28mm long. The electronics are housed securely in a housing mounted onto the extension cable measuring just 35mm x 12mm which also has an LED useful for giving information about the sensor during use.

With the CSmicro we can offer a wider measuring range of up to 1600°C and also a higher ambient operating temperature for the sensing head of up to 180°C without additional cooling. Combined with high quality optics giving small spot sizes, the CSmicro is an extremely versatile group of sensors, and are easily configurable using the optional USB interface and Compact Connect software.
Calibration as well as a full range of accessories are available for the Optris Compact infrared pyrometers.
