The quick exposure time of only 90 μs makes the high speed IR thermometer CT 4M the perfect sensor for measuring fast processes. Due to its short measuring wavelength and a temperature range from 0°C to 500 °C, the pyrometer optris CT 4M, is suitable for measurements of metals, metal oxides, ceramics or materials with unknown or changing emissivity.

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

  • Exposure time: 90 μs
  • Temperature range: 
    0°C to 500°C
  • Spectral range: 2.2 µm - 6.0 µm

Applications: 

The ultra-fast optris CT 4M features a response time of only 300 µs and is thus ideally suited for fast high-volume production and packaging processes (eg. PET preform temperature monitoring) and high-speed traffic safety applications like hot axle box detection on railways. Its wavelength of 2.2 µm to 6.0 µm allow for low-temperature measurements of metas, metal oxides, ceramics and materials with unknown or changing emissvity.
