Optris CTlaser MT for Temperature Measurement Through Flames
The Optris CTlaser MT 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.

Features
- Accurate temperature measurement through flames in the range of 200°C – 1450°C to monitor work pieces inside ovens (heated with fire), to measure inside chemical reactors and to observe the brick temperature in combustion chambers.
- Double laser aiming marks real spot location and spot size up from 1.6 mm at any distance.
- Usable in all modern applications where “size of spot matters”.
- Optics 45:1 with selectable focus, compact sensor head size.
- Cooling and protection accessories for harsh environmental conditions.
- Usable up to 85°C ambient temperature without cooling and automatic laser switch off at 50°C.
