The testo 865 is a professional-grade thermal imager designed for fast, accurate, and reliable thermographic diagnostics—at an exceptionally affordable price. With an infrared resolution of 160 × 120 pixels (enhanced to 320 × 240 pixels via SuperResolution Technology) and a thermal sensitivity of 0.1°C, the testo 865 delivers high-quality thermal images for precise analysis.
Optimized for daily contractor and technician use, it features automatic hot/cold spot detection, testo ScaleAssist for perfect thermal scale adjustment, and an IFOV warner that prevents distance-related measurement errors by visually indicating the exact measurable area.
With its robust design, easy operation, and included carrying case, the testo 865 is ideal for routine maintenance, installation work, troubleshooting, and quality assurance across HVAC, electrical, and building diagnostics applications.
