Testo 872s Thermal Imaging Camera (0560 8725) The Testo 872s Thermal Imaging Camera delivers industry-leading thermal resolution, precision and smart connectivity, making it a strong 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 precise detection of faults in electrical systems, insulation, machinery and structures. Equipped with an integrated laser marker, the 872s highlights the exact measuring point in real time, making on-site analysis fast, accurate and traceable. With thermal sensitivity of 0.05°C (50mK) and a temperature range from -30°C to +650°C, even the smallest heat differences are visible, useful for preventive maintenance and failure det
