Product catalog summary

Overview: The optris® CTvideo 3M is an advanced infrared temperature measurement device designed for non-contact temperature measurement of metals and ceramics ranging from 50 °C to 1800 °C. It features adjustable focus, a patented crosshair laser, and video sighting for precise alignment.

Key Features:

Simultaneous use of video sighting and crosshair laser for easy sensor alignment, suitable for measuring spots from 0.5 mm.
Manual focusing capability for measurement distances starting from 90 mm with optical resolution up to 300:1.
Fast response times starting from 1 ms.
Operable in ambient temperatures up to 70 °C without cooling, with automatic laser switch-off at 50 °C.
Short measuring wavelength of 2.3 μm to reduce errors on surfaces with low or unknown emission rates.
Includes optris Compact Connect software for quick sensor setup, video alignment, and real-time process monitoring.

General Specifications:

Environmental rating: IP 65 (NEMA-4).
Ambient temperature range: -20 °C to 70 °C for the sensing head, -20 °C to 85 °C for electronics.
Storage temperature: -40 °C to 85 °C.
Relative humidity: 10 – 95%, non-condensing.
Vibration and shock resistance: IEC 68-2-6 and IEC 68-2-27 standards.
Weight: 600 g (sensing head), 420 g (electronics).

Electrical Specifications:

Outputs: 0/4 – 20 mA, 0 – 5/10 V, thermocouple J, K.
Alarm output: 24 V/50 mA (open collector).
Digital output: USB 2.0, Ethernet (via optional USB server).
Video sighting: Digital (USB 2.0), 640 x 480 px, FOV 3.1° x 2.4°.
Power supply: 8 – 36 V DC.

Measurement Specifications:

Temperature ranges: Scalable from 50 °C to 1800 °C depending on model (3ML, 3MH, 3MH1-3MH3).
Spectral range: 2.3 μm.
Optical resolution: Up to 300:1.
System accuracy: ± (0.3% of reading + 2 °C).
Repeatability: ± (0.1% of reading + 1 °C).
Temperature resolution: 0.1 K.
Exposure time: 1 ms.

Software and Connectivity:

Includes optris® Compact Connect software for sensor setup, video sighting, and process monitoring.
Automatic snapshots for process control and documentation.
Remote control capabilities via software.

Optical Parameters:

Standard focus (SF) and close focus (CF) options available.
Measurement spot sizes and distances vary based on model and focus type.

Additional Information:

Dimensions and connection modes are specified for both sensing head and electronics.
Specifications are subject to change without notice.
