Product Description

We developed the testo 871 thermal imager together with our experienced professionals to enable you to work quickly and easily with professional thermal imaging technology. You can generate error-free and objectively comparable infrared images using its handy functions. The IFOV warner, testo É›-Assist and testo ScaleAssist mean you can avoid measurement errors and not only effortlessly achieve optimum setting of emissivity (É›) and reflected temperature (RTC) for building thermography, but also of colour scale.

The testo 871 thermal imager€“ smart and networked

The testo 871 thermal imager communicates wirelessly via WLAN with your mobile terminal devices. The testo Thermography App for iOS and Android offers you the possibility of writing and sending reports on site, as well as saving them online, and of using your smartphone or tablet as a second display or for remote control.

The testo 871 delivers even more informative thermal images in combination with the compatible 770-3 clamp meter and the testo 605i thermohygrometer. Both are available separately €“ simply order them straight away along with your testo 871. The measurement results of both measuring instruments can easily be transmitted via Bluetooth. The additional output, current and voltage values of the testo 770-3 clamp meter enable better interpretation of measured temperatures. Measure the air temperature and humidity with the testo 605i and easily detect locations at risk of developing mould using the special humidity palette in the thermal imager via the traffic light principle.

Areas of application of the testo 871 thermal imager

Detect leaks, pinpoint thermal bridges, discover structural defects, identify overheated connections or assess mould damage. The testo 871 thermal imager is ideal for applications in daily maintenance and installation work in trade and industry. Quick, simple and reliable for maintenance and detection of defects.

Technical highlights of the testo 871 thermal imager

Really simple operation with impressive professional thermal imaging technology: the testo 871 thermal imager has the following impressive features:

  • Very good image quality due to high resolution: 43,200 temperature measuring points for precise thermography. Infrared resolution of 240 x 180 pixels €“ extendible to 480 x 360 pixels via integrated SuperResolution Technology
  • Detecting temperature differences from 0.09°C
  • The testo Thermography App enables you to write reports on site, save them online and send them by e-mail, as well as allowing you to use mobile terminal devices as a second display or for remote control
  • Wireless communication thanks to Bluetooth €“ this means you can also wirelessly integrate the readings of the compatible testo 770-3 clamp meter and testo 605i thermohygrometer
  • Built-in digital camera generates a real image in parallel to the thermal image
  • Critical temperature conditions are directly displayed via automatic hot-cold spot recognition
  • The testo ScaleAssist automatically ensures optimum setting of the thermal image scale, which means you generate objectively comparable and error-free thermal images, for example of the thermal insulation behaviour of buildings
  • The testo É›-Assist ensures the correct measurement result by automatically determining and setting the emissivity and reflected temperature
  • The IFOV warner means the distance from the measurement object / measurement spot size is determined and the measurement spot is shown on the thermal image €“ you therefore avoid measurement errors because the camera shows you exactly what you can measure
  • Pro software for image evaluation on the PC
  • You can choose to save thermal images as JPEGs

Delivery Scope

testo 871 thermal imager with radio module for Bluetooth/WLAN, USB cable, mains unit, lithium-ion rechargeable battery, pro software IRSoft (free download), 3 x testo ε-Markers, commissioning instructions, short instructions, calibration protocol and case.

Preventive maintenance :

Ideal for the early identification of imminent malfunctions or defects on plants and machines: Reliably record temperature increases with a thermal imager.

  • Fast detection of critical thermal status (so-called HotSpots) during continuing operation
  • Avoid expensive damage, downtimes and fire risks on plants and machines

Electrical maintenance

  • Test switching cabinets, electrical conditions, photovoltaic plants
  • Evaluate heat status in low, medium and high voltage plants

Mechanical maintenance

  • Identify wear on machines
  • Test motors, bearings, shafts

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

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
