The testo 872s Building Diagnosis Kit is a complete solution for professional building inspections, combining advanced thermal imaging with real-time environmental measurements. The kit includes the testo 872s Thermal Imaging Camera (320 x 240 pixels), the testo 605i Smart Probe for precise humidity and temperature monitoring, and advanced mould detection technology. A smart traffic light indicator (green, amber, red) visually identifies areas at risk of mould formation. With Wi-Fi connectivity, Bluetooth integration, automatic hot/cold spot detection, and IP54-rated durability, this kit delivers fast, accurate, and reliable diagnostics for building professionals.
  • Ultra-Sharp Thermal Resolution – 320 x 240 pixel infrared resolution (upgradable to 640 x 480 pixels with SuperResolution technology) ensures crisp, detailed images.
  • Integrated Laser Marker & Digital Camera – Highlights precise measuring points in the thermal image for better accuracy and documentation.
  • Precise Temperature Detection – Thermal sensitivity of 0.05°C ensures even the slightest temperature differences are visible.
  • Mould Risk Detection Mode – Integrated testo 605i Smart Probe transmits real-time humidity and temperature data, displaying mould-risk areas using traffic light colours.
  • App Connectivity – Use the testo Thermography App for remote control, second display functionality, and instant report creation.
The testo 872s Building Diagnosis Kit is a professional-grade solution for building inspection, energy efficiency analysis, and structural diagnostics. Designed for detecting moisture damage, insulation defects, and HVAC issues, this kit combines the powerful testo 872s Thermal Imaging Camera with the testo 605i Smart Probe, providing real-time data to identify problem areas quickly.

With high thermal sensitivity (50mK), the testo 872s camera can detect temperature differences as small as 0.05°C, making it ideal for pinpointing air leaks, thermal bridges, and overheating electrical components. The integrated laser marker and digital camera allow for precise documentation by capturing visible images alongside thermal readings.

When paired with the testo 605i Thermohygrometer, the testo 872s kit can calculate surface moisture levels and highlight areas at risk of mould formation. The system uses a simple traffic light system (Green = Safe, Amber = Warning, Red = High Risk) to provide instant visual feedback.

The testo Thermography App (for iOS and Android) enables users to stream live images, analyse data, and create reports on-site. Additionally, IRSoft PC software offers advanced thermal image analysis and documentation capabilities.

Built for rugged field use, the testo 872s camera has an IP54-rated sealed casing, four-hour battery life, and 2.8GB internal storage for saving images and videos. Data transfer is seamless via USB or wireless connectivity, ensuring fast and efficient workflow.

The testo 872s Building Diagnosis Kit is an essential tool for professionals looking to improve building efficiency, detect issues early, and ensure structural integrity.

Detecting structural defects and ensuring construction quality

  • Detect potential building defects, prove quality and the implementation of construction measures without contact – with the help of thermal images
  • Test air-tightness of windows and doors
  • Locate insulation errors and cold bridges in a building shell
  • Detect and visualize mould-risk areas

Professional energy consultation

  • Analyze building shells, evaluate energy efficiency, identify energy-saving potential with a thermal imager from Testo
  • Easy recording and documentation of energy loss from buildings
  • Prove faulty insulation and cold bridges without contact, and visualize them in an infrared image
  • Localize untight spots in new buildings quickly and easily in combination with Blower Door

Preventing mould formation

  • Localize mould-risk areas quickly and easily: These areas are presented in red in the imager display when the imager is in humidity mode

Easy checking of heating systems and installations

  • test heating and air conditioning/ventilation systems: Use a thermal imager to identify irregularities in the temperature distribution quickly and easily
  • Localization of the course of heating loops in underfloor heating systems
  • Testo radiators for silting
  • Measure flow and return temperatures

Localize pipe ruptures

  • Reliably determine pipe ruptures with the help of a thermal imager – without unnecessarily opening walls and floors
  • Precise localization of leakages in underfloor heating and other inaccessible pipe systems

Locating leaks in flat roofs

  • Detection of damp in roofs: Based on temperature differences (such as occur mainly in flat roofs), thermal imagers show areas on the roof with sealed-in moisture or damaged insulation
