In the world of field service, HVAC, and laboratory diagnostics, leak detection can often feel like an exercise in trade-offs. You want something reliable but not bulky. You want sensitivity, but not complexity. You want speed, but not a steep learning curve.
Enter the miniTracer™ Portable Leak Detector—a compact, intuitive tool for technicians and engineers who need answers fast, without the fuss.
Why Portability and Simplicity Matter
Imagine you’re on-site—time is tight, and you’re trying to isolate a helium leak. There’s no time to calibrate complex instruments or interpret multi-digit readouts. That’s where the miniTracer™ shines. Designed for fast, visual confirmation of leaks, this handheld detector uses a simple bar graph display and optional audible alerts so you can move quickly and decisively.
Whether you're inspecting valves in a manufacturing facility, checking refrigerant lines in an HVAC system, or maintaining sensitive lab equipment, the miniTracer™ delivers real-time feedback that anyone on your team can interpret—no specialized training required.
Built for Everyday Demands
Let’s face it: leak detection tools don’t always live in pristine conditions. They’re tossed in tool bags, used in awkward positions, and expected to work as hard as you do. That’s why the miniTracer™ is designed to be lightweight and durable, with a rechargeable battery that lasts up to 20 hours—enough to get you through a full shift and beyond.
And unlike soap bubble tests, this device keeps your hands clean while delivering far more reliable results.
High Sensitivity, Zero Guesswork
The miniTracer™ uses thermal conductivity technology to detect even small leaks—as small as 1.0 x 10⁻⁵ cc/sec—along with argon, CO₂, and refrigerants with strong sensitivity across the board. It’s not a data-logging instrument, and that’s the point. It’s for professionals who need quick yes-or-no answers without being bogged down by complex analytics.
The non-quantitative visual bar grows with the leak size, making it easy to scan across fittings, welds, and connections until you find the source. Need extra feedback in noisy environments? Turn on the audible alarm.


Where It Works Best
The versatility of the miniTracer™ makes it a go-to for a wide range of applications:
In the Field
- HVAC and refrigeration systems
- Leak checks on pressure regulators, valves, and welds
- Quality control testing in manufacturing
In the Lab
- Gas chromatographs and detector fittings
- Mass flow controllers
- Cylinder connections and purge systems
Thoughtful Features, No Overload
Despite its simplicity, the miniTracer™ is packed with thoughtful touches:
- Adjustable brightness and peak hold for easy viewing
- Diaphragm pump control for precise sampling
- Soap-free leak detection for a cleaner workflow
Final Thoughts
Not every leak detection scenario requires a high-end, analytics-heavy instrument. Sometimes, what you need most is a tool you can grab and go—with confidence. The miniTracer™ Portable Leak Detector strikes the right balance of simplicity, sensitivity, and portability.
It won’t replace your entire testing bench, but it just might become your favorite everyday tool.
