Optris CT 4M sensor – Infrared

Optris CT 4M sensor for metal applications at low temperatures and/or high speeds.

Optris CT 4M

The fast exposure time of only 90 μs makes the Optris CT 4M infrared sensor the perfect sensor for measurements in fast-paced processes. By measuring in a short wavelength and a measuring range of 0°C to 500°C, this sensor is suitable for measuring metals, metal oxides, ceramics or surfaces of which the emissivity is not known or is constantly changing. The electronics box is equipped with a display and a selection menu with which different analogue outputs can be selected. Various digital interfaces are also available. For more information about the Optris CT 4M, please contact us.
