Refrigerant Leak Detectors (Australia) — Find Leaks Fast, Fix with Confidence

Pinpointing small leaks can make or break a service call. Our pro-grade detectors help Aussie techs work faster and safer across homes, hospitals and commercial plant rooms—from humid Brisbane summers to frosty Canberra mornings.

Key Features & Trade Benefits

  • High sensitivity: Sniff out tiny leaks to cut call-backs and protect charge.
  • Flexible probes: Reach tricky joints in splits, VRF risers and tight cabinets.
  • Audible + visual alarms: Stay alert in noisy plant rooms.
  • Rugged housings: Built to handle dust, humidity and job-site knocks.
  • Long runtime: Rechargeable or long-life batteries for full-day jobs.
  • Multi-refrigerant ready: Works with R22, R134a, R410A, R32, HFO-1234yf and more.

Why These Tools Matter

A reliable detector speeds diagnosis, reduces rework, and supports safer refrigerant handling. Many tradies pair leak detection with a vacuum pump for a clean, dry circuit and use digital manifolds for accurate SH/SC and tight reports.

Compatibility & Use Cases

  • Split systems, ducted and VRV/VRF
  • Refrigeration cabinets and chillers
  • Automotive A/C and cold rooms

Pro Tip

Zero the detector in clean air, then approach joints slowly. Shield the tip from wind and keep a steady probe distance to avoid false positives.

How sensitive should I go?
For HVAC service, choose high sensitivity so you can confirm micro-leaks without guesswork.

Do I still need UV dye?
Electronic sniffers find leaks fast; UV dye is handy for visual confirmation and future checks.
