Outstanding features testo 875 thermal imager:

• Exceptional image quality
  With a temperature resolution of 100 mK or 0.1 C, even minimal temperature differences are shown.
   
• Detection of condensation areas
  Pinpoint potential high risk moisture areas with the testo 875 and avoid mold growth with a thermal scan.
   
• Integrated digital camera
  With the testo 875 view both the digital and IR image simultaneously for faster and more reliable diagnosis of a measurement area.
   
• Automatic Hot/Cold Spot Indicator
  Automatically pinpoint the hottest and coldest spot of a measurement object or area and mark them in the thermal imager display.

Four key advantages of the testo 875 thermal imager:

• Exceptional image quality
  With a temperature resolution of 100 mK, even minimal temperature differences are shown. 
   
• Automatic Hot/Cold Spot Indicator
  Automatically pinpoint the hottest and coldest spot of a measurement object or area and mark them in the thermal imager display.   
   
• Protective Lens 
  A protective lens, made of germanium, attaches to the lens to protect the valuable optics from dirt and scratches.
   
• Integrated digital camera
  With the testo 875, view both the digital and IR image simultaneously for faster and more reliable diagnosis of a measurement area.
   

Five key advantages of the testo 881 thermal imager:

• Excellent image quality
  With a thermal resolution of < 80 mK, the testo 881 delivers high-resolution images in which even the smallest temperature differences are detected.
   
• Indicates high risk moisture areas 
  The testo 881 highlights high risk moisture areas that are potential breeding grounds for dangerous molds
   
• Built-in digital camera with power LEDs
  The 881 features an integrated digital camera that takes a digital image of the measurement area for complete diagnosis and analysis plus the power LEDs provide optimal illumination of dark areas to give you the best visual images. 
   
• Isotherm function
  Marks critical pre-defined temperature values in an area with a color alarm.
   
• Voice recording
  Document important information on site during an IR audit with a voice recording.  Store your comments along with the IR and visual images in the 881 for easier analysis and interpretation of image data using the provided software.
