Testo 872 Thermal Imager Building Inspection Kit

The Testo 872 is a highly advanced camera with 320 x 240 resolution and a thermal sensitivity rating of 60mK, for even greater measurement accuracy of smaller temperature differences. With SuperResolution, the 872 is capable of producing images with a resolution of 640 x 480, meaning each image has over 300,000 individual measurement points.

Suitable for a host of applications, including the building trade, heating construction, electrical and maintenance, the Testo 872 is a highly versatile thermal camera. Examples of specific applications include.

  • Detecting structural defects and ensuring construction quality
  • Easy checking of heating systems and installations
  • Investigating moisture damage
  • Preventing mould formation with traffic light risk indication
  • Pinpoint roof leaks, especially on flat roofs
  • Monitoring and checking solar energy systems to ensure maximum efficiency
  • Mechanical systems such as motors, bearings, conveyors and general process machinery

Ultimate connectivity
In addition to its wide range of application uses, the Testo 872 can be used with the Testo thermography app, available on both Android and iOS devices. Reports can be created and sent via the app, meaning results can be sent straight to the person who needs them, whether this be an engineer on site or a customer. The 872 can also be operated via the app and the smart device can be used as a second screen.

You can also integrate real time readings from the Testo 605i thermo hygrometer (included) to produce a highly effective mould risk survey. The on screen traffic light system clearly shows areas with high, medium and low mould risk. Results can be saved for reporting later, or shown live for immediate action.

Hot and cold spot detection
Automatic hot and cold spot recognition helps flag problem areas quickly and easily, removing the need for timely investigations. This camera also allows the user to view large areas in one go, potentially highlighting multiple critical issues in one snapshot.

Integrated digital camera
An integrated digital camera allows comparison between normal visual images and thermal images side by side. This makes interpreting thermal images much easier, and issues can be pinpointed virtually straight away and marked on the visual image for easy identification on site.

Simplifying emissivity
The Testo 872 makes compensating for emissivity as straight forward as possible. Pre-sets for a range of commonly found materials means the 872 takes the guess work out of setting the correct emissivity level. The 872 can also be used with testo e markers. Simply stick the e marker on the surface to be measured and the camera automatically adjusts the emissivity setting. A manual mode is also available if preferred. The addition of a laser marker means h euser can see exactly what they are measuring.

The feature set and simplicity of the Testo 872 make it an excellent value camera. It takes all the features of the Testo 871 plus adds improved IR resolution, thermal sensitivity, wider field of view and laser marker. Pro software is also included for in depth reporting.
