Description:
The thermal imager testo 890 offers outstanding image quality for the highest thermo-graphic demands. Thanks to the high-quality infrared measurement system with a 640 x 480-pixel detector, thermal images can be recorded in megapixel quality (1290 x 960) using the Super-Resolution technology. This means that even the smallest measurement objects such as electronic components or far distant measurement objects, e.g. on industrial plants, can be safely recorded thermo-graphically in best image quality and high resolution. Even thermal processes can be precisely analyzed over time using the fully radiometric video measurement: all measurement points of the thermal image are available, accurate to the pixel, at all times.
- The testo 890 professional thermal imager means you are ideally equipped for the following applications:
- Safe high-temperature measurement
- Analysis of building shells at a glance
- Regular checks in electrical maintenance
- Precise visualization of critical temperatures on circuit boards
- Carrying out detailed energy consultancy
- Analysis of energy distribution systems
Recommended fields of application
- Detecting structural defects and ensuring construction quality
- Energy consulting (including building shell)
- Leakage detection
- Preventive maintenance
- Research and development
- Power generation and power distribution
