Pyrometer optris CT 3M for low-temperature measurements of metal

Due to its short measuring wavelength and a temperature range from 50 °C on, the pyrometer optris CT 3M, is ideally suited for employment in low-temperature measurements of metals and composite materials. The quick response time of only 1 ms allows for a problem-free use of the metal thermometer in fast processes.

The electronics box of the measuring device allows a flexible terminal device through selectable analog outputs as well as various optional digital interfaces.
