Thermal imager testo 872 – Testo

The Testo 872 thermal imager is a high-performance device crafted for professional industrial and building diagnostics, offering precision, ease of use, and smart connectivity. With an infrared resolution of 320 x 240 pixels—enhanced to 640 x 480 using SuperResolution—it captures detailed thermal data across 76,800 measuring points. The built-in laser marker and digital camera provide clear reference visuals, while critical thermal patterns are instantly recognized through hot/cold spot detection. The device supports wireless integration with the Testo 770-3 clamp meter and 605i thermohygrometer, transmitting complementary data like ambient temperature, humidity, and electrical measurements via Bluetooth. This enhances analysis accuracy in maintenance or energy audits. Additional tools like the IFOV warner and testo ScaleAssist prevent measurement errors by optimizing spot size and thermal scaling. The testo Thermography App enables remote operation, real-time data visualization, and instant report generation, making the 872 an indispensable companion for professionals dealing with thermal bridges, structural weaknesses, overheating components, or moisture risks.
