Fluke introduces new thermal and acoustic imaging for anomaly detection

Together, the new cameras give maintenance teams the ability to detect hidden thermal and acoustic anomalies using compact, mobile-first tools that deliver professional-grade diagnostics directly from a smartphone. The TC03A Thermal Camera helps identify thermal anomalies, while the ii01 Acoustic Camera uses advanced acoustic imaging to pinpoint compressed air leaks.

"Professional diagnostics can no longer be confined to specialized equipment. They need to be available wherever technicians are working. Especially as maintenance teams today are expected to inspect more assets and prevent failures before they occur," said Vineet Thuvara, Chief Product Officer at Fluke. "This innovation makes advanced diagnostics more accessible, giving more technicians the ability to quickly identify hidden thermal and acoustic issues with professional-grade tools that fit the way they work today. This helps organisations shift from reactive troubleshooting to more proactive, data-driven maintenance."

Inspect more. Access less.

Maintenance teams are under constant pressure to inspect more equipment in less time, often without shutting down systems or accessing hard-to-reach components. Infrared thermography and acoustic imaging give technicians a way to survey larger areas, identify potential problems from a distance and focus hands-on investigation where it matters most. Infrared thermography is recognized as a non-contact inspection method that can provide broad inspection coverage and quickly identify thermal anomalies.

High-performance thermal imaging

That ability to inspect without physical contact makes thermal imaging especially useful for assessing multiple assets or areas that are difficult, time-consuming or unsafe to reach. The Fluke TC03A mobile thermal camera combines 384 288 thermal resolution with SuperResolution up to 768 576 to provide detailed images, while manual focus supports inspections across a range of distances, from close-up electronics to equipment that may be difficult to access directly.

Identifying an anomaly is only the first step; technicians also need to understand what they are seeing and determine what action to take. Integrated with the Fluke iSee app, TC03A provides temperature-difference insights, multi-mode alerts and real-time warnings to help technicians quickly assess findings and make informed decisions in the field.

But not every maintenance issue reveals itself through heat. Some problems produce sound instead, requiring a different approach to quickly locate the source.

Fast, precise leak detection

The Fluke ii01 acoustic camera uses SoundMap technology to help technicians locate compressed-air and gas leaks, including in areas that can be difficult to access. With a detection frequency range of 2 kHz to 48 kHz and a detection range of up to 50 meters, depending on site conditions, ii01 can help technicians scan larger areas and pinpoint potential leak sources without inspecting every connection individually.

Once a potential leak is identified, technicians need information that helps them assess the issue on site. A one-key leak mode quickly highlights potential leak sources, while real-time dB readings provide additional diagnostic information to support follow-up inspection and repair.

Compact, connected and built for the field

Whether technicians are looking for abnormal heat across a large facility or tracking down a leak in a hard-to-reach location, the goal is the same: find potential problems sooner, with less time spent accessing individual assets.

Both TC03A and ii01 are part of the Fluke iSee Mobile Series, combining professional inspection capabilities with a mobile-first platform to help technicians identify potential problems, prioritise follow-up and keep maintenance moving.
