Optris CTlaser G5 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 Optris CTlaser G5 model is designed for measuring the temperature of glass accurately in the range 100 to 1650°C making it ideal for all glass applications including tempering, toughening and laminating. 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 10ms. 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.
