Here is the revised product description for the testo 871 Thermal Imager. I have simplified the structure, removed redundancies, and formatted the content for maximum readability.

Product Overview

The testo 871 thermal imager combines professional infrared performance with easy handling. Designed for industry and trade professionals, it allows you to generate error-free, comparable infrared images quickly. With its integrated digital camera and wireless connectivity, you can easily document and share reports directly from the job site.

Key Features

• High Image Quality: Features a 240 x 180-pixel detector. With the integrated SuperResolution Technology, this extends to 480 x 360 pixels (43,200 temperature measuring points).

• Smart Connectivity: The free testo Thermography App allows you to write reports on-site, save them online, and use your smartphone or tablet as a second display.

• Wide Measuring Range: Accurately measures temperatures from -30°C to +650°C.

• Precise Detection: Detects temperature differences as small as 0.09°C.

• Visual Context: A built-in digital camera captures a real image alongside the thermal image for better documentation.

Smart Functions for Better Accuracy

The testo 871 utilizes intelligent features to prevent measurement errors:

• testo ScaleAssist: Automatically optimizes the thermal image scale for objectively comparable images (e.g., checking building insulation).

• testo $\varepsilon$-Assist: Automatically sets the correct emissivity ($\varepsilon$) and reflected temperature (RTC) to ensure accurate results.

• IFOV Warner: Determines the distance to the object and visualizes the measurement spot size, ensuring you only measure what you intend to.

Wireless Integration

Enhance your thermal images by wirelessly integrating data from compatible Testo instruments (sold separately):

• testo 770-3 Clamp Meter: Transmit current and voltage values via Bluetooth to better interpret temperature data.

• testo 605i Thermohygrometer: Transmit air temperature and humidity data to easily detect mold risks using the "traffic light" principle.

Applications

Preventive Maintenance

• Electrical: Check switching cabinets and photovoltaic plants.

• Mechanical: Identify wear on motors, bearings, and shafts.

• Safety: Detect "HotSpots" early to prevent fire risks and costly downtime.

Construction & Building

• Structural Defects: Locate thermal bridges, insulation errors, and air-tightness issues in windows/doors.

• Mold Prevention: Visualize mold-risk areas quickly (displayed in red when in humidity mode).

• HVAC: Check heating loops in underfloor systems, test radiators for silting, and measure flow/return temperatures.

• Leak Detection: Pinpoint pipe ruptures and roof leaks without damaging walls or floors.
