The Testo 872s Thermal Imaging Camera delivers industry-leading thermal resolution, precision, and smart connectivity—making it the perfect tool for HVAC technicians, electricians, industrial engineers, and building inspectors. With a high infrared resolution of 320 x 240 pixels (enhanced to 640 x 480 pixels via SuperResolution), the 872s captures ultra-sharp thermal images, allowing for precise detection of faults in electrical systems, insulation, machinery, and structures.
Equipped with an integrated laser marker, the testo 872s highlights the exact measuring point in real-time, making on-site analysis fast, accurate, and fully traceable. With a thermal sensitivity of 0.05°C (50mK) and a temperature range from -30°C to +650°C, even the smallest heat differences are visible—ideal for preventive maintenance and failure detection.
The built-in digital camera, Wi-Fi connectivity, and Testo Thermography App (iOS/Android) allow you to operate the device remotely, view live data, and generate instant reports from your smartphone or tablet. Bluetooth integration lets you connect with the Testo 770-3 Clamp Meter and Testo 605i Thermohygrometer, combining electrical and humidity readings directly into your thermal reports for a complete diagnostic overview.
With IFOV warning, ɛ-Assist, and ScaleAssist, the 872s ensures error-free measurements, correct emissivity settings, and consistent colour scaling. The rugged IP54-rated housing, 4-hour battery life, and 2x digital zoom make it a reliable companion for demanding field work.
