The infrared video thermometer optris CTvideo 3M is perfectly suited for low-temperature measurement of metals and composite materials starting from 50°C. Parallel use of the video module and the laser sight allow for an easy and exact measuring field marking even if the measuring object is located in hard-to-access areas

  • Temperature range:
    50°C to 1,800°C
  • Spectral range: 2.3 µm
  • Response time: 1 ms
  • Starting at 1290 €

Applications

The video thermometer optris CTvideo 3M, like the related video pyrometers CTvideo 1M and 2M as well as the pyrometer CTlaser 1M / 2M, has been designed for measurement of metallic surfaces, and allows for easy temperature measurement during metal processing within the measurable temperature range of 50°C to 1,800°C.

Additionally, the innovative video module and the laser sight ensure a precise measuring spot adjustment even in hard-to-access processes.

Software

The temperature analysis software optris Compact Connect has been developed specifically for the extensive documentation and analysis of temperature measurement data of our stationary infrared thermometers. It is license-free and included in every pyrometer shipment.
