The CTi 4M high-speed infrared thermometer features an exceptionally fast exposure time of 110 μs, making it ideally suited for precise temperature measurement in high-speed or rapidly changing processes. Due to its unique mid-wavelength sensitivity and a temperature range from 0 °C to 500 °C, the pyrometer optris CTi 4M is suitable for measurements across various materials, like metals, metal oxides, ceramics or any material with unknown or changing emissivity. The pyrometer is a great alternative to LT sensors for high speed and low-temperature applications of challenging materials. The electronics box of the measuring device allows a flexible terminal device through selectable analog outputs as well as various optional digital interfaces.
