The Fluke iSee TC03A Pro is a thermal imaging module designed to transform an Android smartphone or tablet into a thermal camera. With high-quality thermal imaging, accurate temperature readings, and easy-to-use analysis tools, the iSee TC03A helps you find and report faults quickly and confidently. As such, it is ideal for facilities managers, maintenance technicians, and electrical engineers inspecting high-voltage switchgear from a safe distance or tracing heat buildup in densely packed circuit boards.

Equipped with a 384 x 288px infrared resolution, 45mk thermal sensitivity, and a -20°C to +550°C temperature range, the iSee TC03A Pro delivers crisp, detailed thermal images that precisely depict subtle temperature differences often symptomatic of failing connections or components. For even greater image clarity, a SuperResolution function increases the IR resolution to 768 x 576px. Meanwhile, the TC03A Pro’s wide temperature range ensures it is suitable for a variety of applications. Consequently, technicians and engineers can spot failing elements sooner, before they become catastrophic faults.
Designed to facilitate flexible inspections across varied distances, the Fluke iSee TC03A Pro’s minimum working distance begins at just 0.25m (10 inches) and extends up to 20m, making it perfect for inspecting PCBs, as well as power lines. Furthermore, its 1.14 mrad spatial resolution (IFOV) enables detection of spots as small as 0.01m from 10m away, while the manual focus lens allows you to capture details of both near and far targets. Moreover, a 25° x 19° field of view provides sufficient area coverage for efficient inspections.
The Fluke iSee TC03A Pro supports a variety of analysis tools, including spot, line, and area measurement, as well as automatic three-phase temperature delta calculation, which highlights imbalances as soon as they appear. These functions, combined with over-temperature alarms featuring audible, visual, and vibration alerts, help spot emerging problems, enabling you to take action sooner before issues develop into faults causing downtime, potentially saving facilities time and money.
Working in conjunction with the Fluke iSee App, the TC03A Pro captures real-time images and videos that can be integrated into reports or exported for further analysis. Additionally, images, videos, and reports may be shared with colleagues and clients, facilitating streamlined, seamless communication and quicker decision-making.

Built for convenient, reliable daily use in industrial environments, the Fluke iSee TC03A Pro features an IP54 rating against dust and water ingress. Moreover, this pocket-sized thermal camera weighs just 55g and can be connected to your Android smartphone or tablet via a USB-C connection.

The Fluke iSee TC03A Pro Mobile Thermal Camera is a powerful, portable, precise thermal imaging module, ready to transform your smartphone into an inspection tool.
