Elitech CPU-1G HVAC Leak Detector – Fast Halogen Gas Tester for R22/R410A/R134A

Elitech CPU-1G HVAC Leak Detector

Engineered for HVAC technicians, the Elitech CPU-1G blends a traditional coronal sensor with a low energy CPU, delivering stable and fast triggers on halogenated refrigerants including R22, R134A, R410A, and blends. This combination helps you pinpoint leaks quickly while you work through systems of varying ages and configurations, with a focus on real‑world usability rather than theoretical capability.

Designed to perform in busy service environments, the device emphasizes speed, accuracy, and ease of use. Its reliable sensing technology supports quick decision making at the job site, whether you are diagnosing a residential split system or a larger commercial installation. The result is a tool that feels intuitive in your hands and productive in your workflow.

Speed you can rely on

Expect a rapid start with a 3 second response and a brief 6 second warm up. In the field, fast readings translate to shorter service calls and more efficient diagnostics around connections, fittings, and coils.

Precision you can adjust

Seven adjustable sensitivities let you tailor detection to the task. The highest sensitivity reaches 0.11 oz per year, helping you balance safety margins with the practical needs of different refrigerants and system pressures.

Pro-grade probe and modular sensor

A 14 inch flexible stainless steel probe reaches tight spaces, while two alternative sensor tips provide testing flexibility. The modular sensor design supports straightforward maintenance and faster component swaps when needed.

Power and support you can count on

Powered by two C alkaline batteries, included, the CPU-1G is built for field use. For ongoing assistance, 24/7 US technician support via email and phone is available to address questions or setup tips.

Wide refrigerant coverage

Designed to work with R11, R22, R134A, R404a, R410A and all halogenated refrigerants including blends, the CPU-1G offers broad compatibility for diverse HVAC systems and service scenarios.

• Stable and fast triggers across major halogenated refrigerants
• Long-range reliability during field service
• Compact, durable construction with a flexible probe

The modular design supports routine maintenance without disrupting your workflow. With a robust build and straightforward components, you can keep focus on diagnosing leaks rather than equipment downtime.

Real world use cases

In residential service, locate leaks around evaporator coils and line connections behind access panels. In commercial settings, the long probe helps you reach congested mechanical rooms and tight circuitry without dismantling large assemblies. The adjustable sensitivity helps you adapt to noisy environments or detection of very small traces while staying within practical expectations.

What you get and how it helps

• Two C alkaline batteries included for immediate use
• Two sensor tips for diverse testing needs
• 24/7 technical support for guidance and setup tips

Whether you are troubleshooting a single unit or inspecting a fleet of systems, the Elitech CPU-1G offers a practical balance of speed, precision, and ease of maintenance without making guarantees about outcomes. It is a tool to aid your inspection workflow and support informed decisions on leak testing.
