Testo 890 Professional Thermal Imager Kit with 3 Lenses
The premium Testo 890 3-lens kit is a flagship thermography system engineered for high-end industrial diagnostics, structural asset protection, and deep facility energy consultancy. Driven by a high-resolution 640 x 480 pixels infrared detector with an exceptional thermal sensitivity of <40 mK, it visualizes the finest temperature micro-variances. This comprehensive package includes three interchangeable lenses (such as the 42° x 32° Standard and 15° x 11° Telephoto options) to adapt seamlessly from close-range inspections to medium or long-range targets. Enhanced with testo SuperResolution technology, the thermal image resolution scales up to 1280 x 960 pixels, offering unmatched precision for electrical maintenance and critical electronic board thermal mapping.
Industrial Applications
- Heavy Electrical System Auditing: Regular predictive maintenance scanning of high-voltage lines, sub-stations, and thermal connections from a safe operational distance.
- Advanced Building Shell Analysis: Large-scale non-destructive imaging of entire building envelopes to isolate thermal bridges, moisture fields, or mould risk areas.
- High-Temperature Infrastructure Tracking: Safe, high-precision evaluation of industrial furnaces, refineries, and chemical reactors up to 1200 °C using the high-temperature option.
