The Testo 865s Thermal Imaging Camera is the perfect entry-level thermal imaging solution for professionals who demand precision and reliability. Designed for electricians, HVAC technicians, and building inspectors, this thermal imager captures detailed infrared images with 160 x 120 pixel resolution (upgradable to 320 x 240 pixels with SuperResolution technology), ensuring accurate temperature measurement from -20°C to 280°C.


With thermal sensitivity of 0.1°C, the testo 865s detects even the smallest temperature variations, making it ideal for pinpointing insulation gaps, overheating components, pipework leaks, and structural defects. Automatic hot/cold spot recognition simplifies diagnostics, highlighting temperature anomalies instantly.


Built for fast and efficient work, the testo 865s features intuitive one-handed operation with a simple, ergonomic design. The IFOV warning system ensures accurate measurements, while the ScaleAssist function automatically optimizes the thermal image scale, preventing interpretation errors. Thermal images can be stored on the large 2.8GB internal memory and transferred to a PC via USB for in-depth analysis using Testo’s free IRSoft software.


Durability is key for professionals working in demanding environments, and the testo 865s is built to last. With an IP54-rated splash-proof and dustproof casing, it withstands the rigors of daily use. The rechargeable battery provides up to 4 hours of continuous operation, ensuring you can complete inspections without interruptions.


Whether you're performing building inspections, electrical diagnostics, or HVAC system analysis, the testo 865s delivers high-quality thermal imaging at an unbeatable price-performance ratio.
