Testo 890 - Thermal Imager
Product Description
- Inspecting high-voltage lines
- Pinpointing hotspots in solar parks (which can indicate defective cells, for example)
- Detecting irregularities in large industrial plants (such as refineries)
All the important information about the testo 890 thermal imager with super-telephoto lens
testo 890 thermal imager:- Up to 307,200 temperature measuring points: a detector size of 640 x 480 pixels guarantees accurate detection. SuperResolution technology even boosts image quality to 1280 x 960 pixels
- You can also choose to save thermal images as JPEGs
- Process analysis package (optional): the combination of fully radiometric video and sequence capturing in the instrument enables wireless measurement and easier handling at the measuring location
- The camcorder design with wrist strap, along with the rotatable, fold-out display, makes taking images considerably easier. This makes it possible for a wide variety of camera angles, as well as one-hand operation
- Panorama image assistant: individual images are combined into a panoramic image as soon as they are taken. This means, for instance, that you can take thermal images of entire building shells without having to laboriously compile them or assess them individually
- SiteRecognition technology: with similar measurement objects, the thermal imager identifies measuring locations immediately, assigns them automatically and archives them accordingly
- Voice recording (as comments on the images) possible with headset which is included in the scope of delivery
- Integrated digital camera with power LEDs: you can take well-lit, real images to go with every thermal image - making documentation and assignment easier
- FeverDetection (optional): use the assistant to check people for high body temperature in public places and in means of transport – for public health protection
- Exchangeable lenses optionally available (42° standard/wide-angle lens and 15° telephoto lens)
6.6° x 5° super-telephoto lens
- Compatible super-telephoto lens for the testo 890 thermal imager
