Thermal imager – testo 890 (640 x 480 pixels, manual/auto focus, laser, 1 lens selectable)

Advantages of the testo 890 thermal imager

Resolution: 640 x 480 pixels and can be enhanced up to 1280 x 960 pixels with SuperResolution technology

Thermal sensitivity < 40 mK: allows you to distinguish even the smallest temperature differences

You can also choose to save the thermal image as a JPEG.

The testo 890 with wrist strap, together with the rotatable, foldable display, makes your work much easier. This feature allows you to carry out the measurement task from any angle.

Panorama image assistant: individual images can be combined into a panoramic image. This makes it easy to evaluate comprehensively and accurately

SiteRecognition technology: for identical measurement objects, the testo 890 thermal imager can identify measurement locations immediately, automatically assigning and storing them with each respective measurement result

High temperature option: measuring range can be extended up to 1200 °C

Special measurement mode to detect areas prone to mold when used in conjunction with a compatible wireless moisture probe (optional order). The display will warn of mold risk by color (red, yellow, green).

Lenses can be flexibly changed depending on usage needs.

Voice recording (as well as comments on captured thermal images) is possible using the included headset.

Built-in digital camera with LED light: allows you to capture clear real-time images along with thermal images

Auto focus for easy one-handed operation and to avoid blurry images

Minimum focusing distance 10 cm

You can choose 1 of the following 3 lenses:

Standard lens 42° x 32°: Ideal for inspecting measurement objects at close range, large field of view

25° x 19° Lens: Ideal for use in applications involving maintenance, evaluation and prevention

15° x 11° telephoto lens: Can check the temperature of objects at medium and long distances
