Why Choose RefriLeak
Professional Diagnostic Precision
The RefriLeak LD-100+ is a premium heated diode refrigerant leak detector engineered for UK technicians who demand uncompromising accuracy. Unlike basic consumer-grade sniffers that trigger false alarms, our advanced heated diode sensor isolates specific halogenated gases, allowing you to pinpoint leaks as small as 3g/y. Whether you are tracing an elusive fault in a commercial heat pump or conducting routine vehicle AC diagnostics, this tool drastically reduces troubleshooting time.
Unrivalled Refrigerant Compatibility
Designed to be the ultimate hvac refrigerant sniffer, this device offers broad compatibility across legacy and modern gases. It seamlessly detects CFCs, HFCs, HCFCs, HCs, and HFOs (including R134a, R410a, and R1234yf). If you are looking for a reliable freon leak detector that outperforms standard models from competitors like Inficon or Fieldpiece without the inflated price tag, the Elitech LD-100+ architecture within our unit delivers robust, day-to-day workshop reliability.
Built for the Trade
Featuring a rugged, ergonomic design and a flexible 365mm stainless steel probe, this detector easily navigates tight engine bays and complex commercial refrigeration arrays. Visual and audible leak indicators scale with concentration, ensuring you can accurately zero in on the source of the leak even in noisy industrial environments.

Customer Reviews
Brilliant bit of kit. As an automotive AC specialist, finding a reliable heated diode refrigerant leak detector that actually picks up tiny R1234yf leaks without false alarming on engine oil has been a game changer. Highly recommend.
Next day delivery was spot on. I work on large commercial refrigeration units and the 3g/y sensitivity on this is exceptional. Easily outperforms the basic sniffer I was using before.
Purchased this for our heat pump installation team. The flexible probe is robust and gets into incredibly tight spaces behind the indoor units. A truly professional hvacr gas sniffer.
Very accurate and the build quality feels premium. It does take about 30 seconds to warm up which is slightly longer than my old corona detector, but the accuracy of the heated diode makes it worth the wait.
I was looking at the Inficon models but decided to try this based on the specs. Glad I did. It pinpointed a micro-leak on an R410a system in minutes that my previous tool completely missed.
Excellent automotive ac leak detector. The battery life is solid for a full day in the workshop. Only minor gripe is the carry case is a bit bulky for my main tool bag, but it protects the unit well.
Great value for money. As an F-Gas registered engineer, having a dependable 3g per year leak detector is mandatory. This hits all the marks for compliance and daily reliability.
