Optris CSmicro 3M Miniature Infrared Pyrometer

The CSmicro 3M is a miniature infrared temperature sensor designed for the measurement of the temperature of metals at low temperatures from 50 to 600°C. The short wavelength sensitivity of the sensor enable measurement to be taken accurately where the emissivity is low or variable.
The CSmicro 3M has the smallest sensing head of any infrared sensor in the world making it ideal for applications where space is at a premium. The electronics for the sensor are mounted in a discrete moulded pod on the cable allowing the sensing head to be extremely small at just 14mm diameter x 28mm long. This infrared pyrometer is 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.
