All important info on the testo 890-2 thermal imaging camera

testo 890-2 thermal imaging camera:
  • Up to 307,200 temperature measuring points. Large detector size: 640 x 480 pixels for pinpoint detection. Superior image quality: SuperResolution technology enhanced quality to 1280 x 960 pixels!
  • Thermal sensitivity < 40 mK: shows even the tiniest temperature variations
  • Thermal images can also be saved as JPEG
  • Process analysis package (optional): a combination of fully radiometric video and sequence storage in the camera enables you to carry out cable free measurements making it infinitely easier to handle the camera
  • Camcorder design with handstrap and tilt/swivel display for easier imaging. Allows you to operate the camera comfortably with one hand operation and take images from numerous different angles
  • 42° wide angle lens for larger field of view
  • Panorama image assistant: individual images are combined directly to create a panorama image. This allows you to capture the whole shell of a building, for example, without having to laboriously put together or analyze individual images
  • SiteRecognition technology: the thermal imaging camera recognizes measuring sites immediately in case of similar measuring objects, matches them automatically and archives them accordingly
  • Optional high temperature measurements up to 2,192 °F: The high temperature option allows you to increase the measuring range flexibly up to 2,192 °F
  • Special measuring mode for detecting places where mold can grow easily. Enter the air temperature and RH manually to calculate the dew point in the room. The surface temperature that the camera has measured is then compared to the dew point value that has just been determined. The risk of mold is shown on the display in traffic light colors (red/amber/green). It’s even easier with the optional humidity sensor: because the air temperature and humidity are transferred automatically, there is no need to enter these values
  • Voice annotations (as comments on the images) with headset possible, headset included
  • Onboard digital camera with power LEDs for perfectly illuminated real images to go with each of your thermal images. Makes documenting and correlating the images much easier
  • Autofocus for convenient one-hand camera use and fewer blurred images
  • Interchangeable lenses (i.e. for use with the optional telephoto)
  • Minimum focus distance 4 in.

Checking as part of electrical maintenance

In electrical installations or cables, increased temperatures are always an indication of an overload, an imminent malfunction or an existing defect. Testo thermal imagers facilitate evaluation of the heat status of low, medium and high-voltage systems. Thermographic images lead to the early detection of defective components or connections, so that the necessary preventive measures can be introduced in a targeted way. Thermography therefore minimizes dangerous fire risks and prevents costly production downtimes.
Typical applications for the thermal imager:
  • Checking switch cabinets
  • Checking electrical connections
  • Monitoring and checking photovoltaic systems
  • Checking as part of mechanical maintenance

Analysis of power distribution systems

Avoiding the failure of power distribution systems is absolutely essential due to the far-reaching consequences. Faulty connections on high voltage masts can be particularly critical here. These transitions to high-voltage lines, which sometimes occur at great distances, can only be clearly identified with a sufficiently large detector or a telephoto lens. This is the only way to obtain the necessary degree of detail to enable error-free analysis of the thermal image.

Analysing building shells at a glance

The task of taking thermal images of large buildings poses several challenges for users. Spatial restrictions due to walls, roads or safety zones around neighbouring buildings can make it impossible to capture the measuring object in a single image. In such cases, Testo thermal imagers help users obtain the necessary overview. The panorama image assistant can be used to combine several images of the building shell taken at close range into a single thermal image. Users can therefore identify thermal irregularities at a glance across the entire building shell with a high degree of detail.

Providing comprehensive energy advice

In building thermography, infrared technology is particularly suitable for quick and effective analysis of energy losses in buildings’ heating or air conditioning systems. Thanks to their high temperature resolution, Testo thermal imagers provide detailed images of inadequate insulation and thermal bridges. They are ideal for the recording and documentation of energy losses on outer windows and doors, roller blind casings, radiator niches, in roof structures or the entire building shell. Testo thermal imagers are the perfect measuring tool for comprehensive diagnosis and maintenance uses, and whenever providing energy consultation services.

Making it possible to see critical temperatures on circuit boards precisely

In the field of research and development, thermal imagers are also used for the targeted analysis of temperature distribution, e. g. on circuit boards. Electronic components on circuit boards are getting smaller and smaller – thus increasing the challenges with regard to heat dissipation. Only premium-quality thermal imagers with a really fine geometric resolution are suitable for this task. Analysis of the heating and cooling behaviour over time is also helpful for optimisation and this can be carried out using the Testo thermal imager's video measurement
