Optris CTlaser 05M Infrared Pyrometers

The Optris CTlaser dual laser sensors offer a greater degree of flexibility in available options. The electronics are housed in a remote enclosure with a selection of output and digital interface options. The electronic box also includes its own digital LCD display showing temperature and alarm conditions. All configuration options are set via the front panel removing the need to use a PC to configure the pyrometer. Shorter wavelength versions are also available specifically designed for use with metals, glass and plastic films.  All Optris CTlaser pyrometers come with a choice of optics to best suit your requirement.

The new CTlaser 05M has been developed for the temperature measurement of molten metals in the 1000 to 2000°C. The very short wavelength sensitivity of this sensor reduces the effects of very low emissivity and atmospheric vapour effects. Selectable optics allow you to choose the most appropriate spot size for your application with a smallest spot of 1mm possible. The sensor also has a very fast response time of just 1ms. It is also easy to connect our innovative USB interface which allows simple configuration and on screen measurement with the included Compact Connect Windows software.
Calibration as well as a full range of accessories are available for the Optris High Performance infrared pyrometers.
