Thermal Imager testo 890

thermal imager testo 890 testo 890 Megapixel thermal images and fully radiometric video measurement

The thermal imager testo 890 in the new ergonomic camcorder design offers excellent image quality for even the highest demands. With the 640 x 480 pixel detector (in combination with the SuperResolution technology, the testo 890 can even record extremely high-resolution thermal images in megapixel quality), and the excellent thermal sensitivity of < 40 mK, even the smallest or very distant measurement objects and the finest temperature differences are made visible in the high-resolution infrared image.

super-resolution 4x testo 890: Thermography now with SuperResolution technology, also in high-resolution megapixel quality

With the optionally available SuperResolution technology, you improve the infrared image quality of the testo 890 by one class in no time. Four times more measurement values and a geometric resolution of the infrared image improved by a factor of 1.6 means for you: higher-resolution images (1280 x 960 Pixel) in megapixel quality, excellent thermal sensitivity (< 40 mK) and even more reliability in your measurement.


Outstanding Performance In Every Application testo 890

infrared image high resolution See all the details in the infrared image in high resolution even at a great distance.

Large distances to the measurement object require either a reduction of the distance or superior technology. In many situations, thermographic measurement technology is the solution: because faulty connections in high-voltage masts simply cannot be examined from close up. With the high-resolution detector and the high-quality telephoto lens of the testo 890, one obtains the necessary attention to detail in the thermal image at such distances and can thus carry out meaningful analyses.

radiometric video measurement Make critical temperature curves of the smallest components visible in high resolution: fully radiometric video measurement
Electronic components are becoming smaller and smaller, the demands on heat withdrawal are increasing. For optimization purposes, an examination of temperature conditions using a high-resolution thermal imager with high thermal sensitivity is expedient, and the analysis of warming and cooling behavior over defined time intervals is often required. The testo 890 offers both and the possibility of recording fully radiometric video sequences.

The advantages of testo 890
Detector size 640 x 480 pixels
With 307,200 temperature measurement points, the measurement objects are detected in excellent image quality, clearly and precisely.
super-resolution technology SuperResolution technology (to 1280 x 960 pixels)
SuperResolution technology improves the image quality by one class, i.e. the resolution of the thermal images is four times higher.
thermal sensitivity Thermal sensitivity < 40 mK
Thanks to an excellent temperature resolution of < 40 mK, even the smallest temperature differences are visible.
Large field of view thanks to 42 lens
With the 42 standard wide-angle lens, large image sections are immediately recognized, and the temperature distribution of the measurement object recorded at a glance.
 panorama image assistant Panorama image assistant
For large measurement objects, the panorama image assistant allows the analysis and documentation of a total image stitched together from many individual images. There is no need to administer, view and compare several images.
site-recognition technology SiteRecognition technology
For repetitive thermography of similar measurement objects, the SiteRecognition technology offers the direct recognition, allocation and archiving of the measurement sites, as well as the automatic allocation and archiving of the the thermal images.
High temperature up to 1200C
With the high temperature option, the measuring range can be flexibly extended up to 1200 C.
Fully radiometric video measurement incl. logger function (via USB)
With the fully radiometric video measurement thermal processes can be thermally analyzed in real time (also periodically and event based). For every instant, all temperature measurement points are exactly available per pixel.
