Why Choose Our Refrigerant Leak Detectors?

• Ultra‑sensitive detection - Select from heated diode, infrared, or electronic sensor leak detectors that detect even trace refrigerant leaks (R22, R134a, R410A, R32, and more)
• Fast response and low false alarms - Our units pinpoint leaks quickly to minimize system downtime
• Portable and rugged - Many models are handheld and built for field use in HVAC / refrigeration service work
• Wide brand selection - We stock trusted names such as Fieldpiece, Robinair, Inficon, Testo, CPS, Javac, and more
• Australian stock and support - Shipped from Australia, with local warranty support and fast delivery to your site

How to Choose the Right Refrigerant Leak Detector

• Sensor type - For general use, a heated diode is versatile; for higher sensitivity and longevity, an infrared sensor is ideal
• Sensitivity - Look for models that detect leaks down to ppm (parts per million) levels
• Selectivity - Some detectors ignore background gases (water vapor, solvents), reducing false triggers
• Display and alerts - Audible, visual, and digital readouts help you quickly locate leaks
• Durability - Field conditions demand rugged casings and battery life
