Testo 871 Professional Smart Thermal Imager
The Testo 871 thermal imager flawlessly combines a high-performance infrared pixel detector with smart, networked measuring capabilities. Engineered specifically for operators requiring quick, easy, and objective testing, this device generates premium error-free data. Incorporating advanced testo SuperResolution, its resolution dynamically upgrades to deliver sharp, descriptive thermal graphs. With proprietary functions like testo ScaleAssist and testo ɛ-Assist, the imager dynamically guarantees optimum scale configurations and exact emissivity adjustments. It offers wireless network capabilities over WLAN and Bluetooth for integrating external measurement accessories like optional clamp meters or humidity probes.
Industrial Applications
- Building Insulation Audits & Energy Tracking: Rapidly detect insulation leaks, discover invisible structural failures, and isolate critical thermal bridges.
- Preventative & Industrial Maintenance: Identify overheating electrical connections, evaluate plant systems under full load, and troubleshoot high-risk components.
- Mold Prevention & Assessment: When paired with smart environmental probes, it maps critical moisture boundaries to highlight risk sectors before structural damage emerges.
