Refrigerant Leak Detectors | R32, A2L & HVAC Leak Tools

Refrigerant Leak Detectors for HVAC & Refrigeration Work

Shop refrigerant leak detectors, UV dye tools, bubble sprays and tracer-gas options for HVAC/R diagnostics across Australia. This collection suits refrigeration and air-conditioning technicians, apprentices, workshops and informed buyers who need a practical way to locate leaks on split systems, refrigeration systems and general service jobs.

If your workflow also includes charging, recovery or evacuation verification, browse our refrigerant gauges, recovery units and vacuum gauges. For brand-specific options, see Fieldpiece, Robinair and Testo.

How to choose the right leak detector

• Start with the method: electronic detectors are the main trade option for finding the general leak area quickly, while bubble solutions and UV dye are better for confirming the exact point of leakage. If you want a clearer breakdown of when each method makes sense, see our Types of Leak Detectors Guide. If you also want a practical workflow for using one properly on the job, read How to Use an HVAC Leak Detector.
• Check refrigerant compatibility: for R32 and other A2L-related work, only choose tools where the product page clearly states the appropriate compatibility or intended use.
• Match the job type: routine service calls often suit a handheld electronic detector, while intermittent leaks may need UV dye or a second confirmation method.
• Think about false positives and workflow: infrared and heated diode models suit different user preferences, environments and budgets.
• Don’t forget confirmation: many technicians use an electronic detector to narrow the area, then a bubble solution to show the exact flare, joint or component.

Shop leak detection by method

• Electronic refrigerant leak detectors: the go-to option for most HVAC/R service work when you need to find the general leak area quickly.
• Infrared detectors: a strong option for technicians wanting a more premium electronic detector with stable day-to-day performance.
• Heated diode detectors: a common trade choice for general refrigerant leak finding.
• UV dye and visual tracing: useful for slow, intermittent or hard-to-repeat leaks where visual confirmation helps.
• Bubble solutions: ideal for pinpoint confirmation once you’ve narrowed the area down.
• Tracer-gas tools: suited to specialist leak-finding workflows where hydrogen/nitrogen methods are being used with the correct equipment.

Compatibility and safety notes

Leak detectors are diagnostic tools, not a substitute for proper pressure testing, evacuation verification or compliant refrigerant handling. Always check the product page for the refrigerants, gases and applications the tool is intended for.

For Australian refrigerant work, use appropriately licensed technicians where required and follow the current ARCtick guidance. After refrigeration-circuit work, systems must be leak tested before recharge, and refrigerant must not be introduced just for leak testing.

FAQs

Are these leak detectors suitable for R32?

Some are, but not every detector should be assumed suitable. Check the product page carefully for R32, A2L or application-specific wording before ordering.

What is the difference between infrared and heated diode detectors?

Both are electronic methods for refrigerant leak finding. In practice, many buyers choose based on workflow preference, budget and the type of service work they do most often. For a broader comparison of features, sensitivity, workflow fit and budget considerations, see our leak detector buying guide.

Do I still need bubble solution if I have an electronic detector?

Often yes. Many technicians use an electronic detector to find the general leak area, then use a bubble product such as Viper Big Blu or Errecom Best Bubbles to verify the exact point.

Does a leak detector replace a nitrogen pressure test?

No. A leak detector helps locate the leak. Pressure testing and repair verification still matter as part of a proper service workflow.

Should I buy UV dye or an electronic detector?

For most day-to-day HVAC/R service work, an electronic detector is usually the first purchase. UV dye can be useful for intermittent or very slow leaks that are harder to catch in a single pass.

Can DIY users buy these tools?

Some can, but refrigerant handling in Australia is regulated. Product purchase is not the same as being authorised to perform refrigerant work.
