The Fluke iSee TC03A is a thermal imaging module that connects to your Android smartphone or tablet via a USB-C interface, transforming your smart device into a thermal camera. The Fluke iSee is designed to help facilities managers, maintenance technicians, and electrical engineers quickly and confidently find and report faults. As such, it provides high-quality thermal imaging, accurate temperature readings, and easy-to-use analysis tools, making it ideal for both inspecting high-voltage switchgear from a safe distance and tracing heat buildup in densely packed circuit boards.

The Fluke iSee TC03A delivers crisp, detailed thermal images that precisely depict subtle temperature differences often symptomatic of failing connections or components. To this end, it features a 384 x 288px infrared resolution, 50mk thermal sensitivity, and a wide -20°C to +550°C temperature range that covers a variety of applications. The Fluke iSee TC03A also features a SuperResolution function that increases the IR resolution to 768 x 576px, offering even greater clarity. As a result of the Fluke iSee TC03A’s thermal capabilities, technicians and engineers can spot failing components sooner, before they become catastrophic failures.
Offering a working distance of 0.25m (10 inches) up to 20m and a 25° x 19° field of view, the iSee TC03A is designed to facilitate efficient inspections across a wide range of distances and areas. This, combined with a 1.14 mrad spatial resolution (IFOV), which allows you to detect spots as small as 0.01m from 10m away, and a manual focus lens for capturing details on near and far targets, makes the iSee TC03A perfect for checking tiny PCBs and distant power lines.
Spot, line, and area measurement tools, combined with an automatic three-phase delta calculation which highlights imbalances as they appear, and an over-temperature alarm with audible, visual, and vibration alerts, help you spot anomalous temperatures indicative of potential problems sooner and more easily. This enables you to take action before issues develop into downtime-causing failures, potentially saving sites time and money.
Using the TC30A alongside Fluke’s iSee app, you can capture images and videos in real-time, which may be exported or integrated into reports. Images, videos, and reports can also be shared with colleagues and clients, streamlining communication and speeding up decision-making.

This pocket-sized thermal camera weighs just 55g and is built for daily use in industrial environments. To this end, it features an IP54 rating against dust and water ingress.

Precise, powerful, and portable, the Fluke iSee TC03A Mobile Thermal Camera transforms your Android smartphone or tablet into an inspection tool.
