Product Description

The testo 885 thermal imager with super-telephoto lens enables Testo to offer an instrument which is suitable for carrying out thermography over long distances. The super-telephoto lens makes it feasible to accurately record distant measurement objects. The thermal imager is therefore particularly suitable for:

  • Inspecting high-voltage lines (even the smallest connections can be checked from a great distance)

  • Locating hotspots in solar parks (e.g. to detect defective cells)

  • Detecting irregularities in large industrial plants (e.g. refineries)

Discover all the technical features of the testo 885 thermal imager with super-telephoto lens 

testo 885 thermal imager:

  • Detector size 320 x 240 pixels: with 76,800 temperature measuring points, measurement objects are photographed extremely clearly and accurately, in outstanding image quality

  • SuperResolution Technology to 640 x 480 pixels: this feature takes the image quality to the next level – making the resolution of the thermal images four times higher

  • Integrated digital camera with power LEDs: ideal for assigning thermographic images to real images and thus for creating perfect documentation for customers

  • User-friendly operation: ergonomic rotating handle and rotatable, fold-out display

  • You can also choose to save thermal images as JPEGs

  • Panorama image assistant: in the case of large measurement objects, the panorama image assistant enables analysis and documentation of the measurement with an overall image compiled from multiple individual images. So there is no need to manage, view and compare a large number of images, which can be laborious. It enables images of entire building shells

  • SiteRecognition technology: for recurrent thermal imaging of similar measurement objects, SiteRecognition technology offers immediate measuring location identification, as well as automatic assignment and archiving of thermal images

  • Process analysis package (optional): the combination of fully radiometric video and sequence capturing in the camera enables wireless measurement and easier handling at the measuring location

  • FeverDetection (optional): use the assistant to check people for high body temperature in public places and in means of transport – for public health protection

  • Lens exchange possible (e.g. to use optionally available additional lenses)

  • Voice recording with headset

  • Auto-focus for one-handed operation and to prevent blurred images

  • Professional software testo IRSoft: allows the thermographic images to be analyzed on the PC

5° x 3.7° super-telephoto lens:

  • Compatible super-telephoto lens for the testo 885 thermal imager

  • Small field of view (5° x 3.7°) for maximum resolution of particularly distant objects

  • Easy to handle: no additional lens holder needed
