Optris CT 3M
Product Information
Due to its short measuring wavelength and a temperature range from 50°C on, the pyrometer optris CT 3M, is ideally suited for employment inlow-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.
- Temperature range:
50°C to 1,800°C - Spectral range: 2.3 µm
- Response time: 1 ms
Applications:
The IR thermometer optris CT 3M has a measuring wavelength of 2.3 µm and is thus employed in temperature measurements of metallic surfaces and composite materials in processing. Especially its low temperature range from 50°C on make the temperature sensor a popular measuring device for every kind of low-temperature measurement of metals.
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.
