The following measuring activities can be performed with this professional thermal imager with a super-telephoto lens and two additional lenses (free choice between standard, 25°, and telephoto lens):
- Inspecting high-voltage lines: the super-telephoto lens enables you to inspect even the smallest of connections from a long, safe distance
- Pinpointing hotspots in solar parks (to locate defective cells)
- Detecting irregularities in large industrial plants
- Safe high-temperature measurement
- Analysis of building shells at a glance
- Detecting critical temperatures on circuit boards
- Regular checks in electrical maintenance
- Analysis of energy distribution systems
- Carrying out detailed energy consultationsAll the important information about the testo 890 thermal imager and its lenses
testo 890 thermal imager:
Up to 307,200 temperature measuring points can be accurately detected with a 640 x 480 pixel detector. Even to 1280 x 960 pixels, SuperResolution technology improves image quality.
Even the slightest temperature variations may now be noticed thanks to thermal sensitivity of less than 40 mK.
Thermal photos can also be saved as JPEGs.
Package for process analysis (optional): Wireless measurement and simpler handling at the measurement site are made possible by the instrument’s combination of completely radiometric video and sequence capture.
The rotatable, fold-out display and wrist strap on the camcorder make capturing pictures more simpler. This enables a wide range of camera angles in addition to one-handed control.
Immediately after being taken, separate photos are stitched together to create a panoramic image. For example, you can capture thermal photos of complete building shells without having to tediously compile or evaluate each one separately.
SiteRecognition technology: When measuring objects are similar, the thermal imager instantly recognises the measuring places, assigns them automatically, and archives them as necessary.
Option for high temperatures: the measuring range may be increased to 1,200°C.
By manually entering the room’s dewpoint and ambient temperature and humidity, a special measuring mode for locating mold-prone areas can be used. The dewpoint is then used to compare the surface temperature value that the camera has recorded. Now, the display uses the red, yellow, and green traffic light colours to indicate the risk of mould. It is simpler with the optional radio humidity probe: Automatic reading gearbox eliminates the requirement for manual humidity and ambient temperature input.
Use the assistant to check people for high body temperatures in public areas and on transportation in order to preserve the public health. FeverDetection.
The lens may be changed.
Voice recording is possible using a headset that is part of the delivery, as comments on the photographs.
Integrated digital camera with power LEDs makes it possible to take actual, well-lit pictures in addition to every thermal image, simplifying documentation and assignment.
Autofocus for simple one-handed use and sharper photos
Focus distance requirement: 10 cm.Lenses
In addition to the super-telephoto lens, in this kit you are free to choose two additional lenses from a total of 3 that are available:
6.6° x 5° super-telephoto lens (included in the kit):- Small field of view (5° x 3.7°) for maximum resolution of particularly distant objects
- Easy to handle: no additional lens holder needed
42° x 32° standard lens (optionally included in the kit as a second or third lens):
- Ideal for inspecting closer measurement objects
- Large field of view
25° x 19° lens (optionally included in the kit as a second or third lens):
- Ideal for use in applications involving preventive maintenance
15° x 11° telephoto lens (optionally included in the kit as a second or third lens):
- Makes it possible to take outstanding images of measurement objects at medium and longer distances
