Elitech CLD-100 Refrigerant Leak Detector – handheld halogen detector, 8.26” flexible probe, 6 sensitivity levels

Compact and built for technicians, the Elitech CLD-100 (upgraded from the WJL-6000) combines a traditional corona sensor with an improved analogue circuit to deliver fast, reliable alerts on R11, R22, R134a, R404A, R410A and other halogenated refrigerants. It warms up in about six seconds, offers six sensitivity settings, and uses a flexible 8.26-inch probe to access tight spots in automotive and building HVAC systems.

How quickly will the CLD-100 detect a refrigerant leak?

The detector is designed for near-instantaneous response once warmed up, with a preheat time around six seconds. Audible and visual alarms trigger rapidly when halogenated gases are detected so you can pinpoint leaks without long waits.

• 6 second preheat for fast readiness
• Instant alarm activation on sensor trigger
• Six sensitivity levels to refine detection speed vs. false alarms

What refrigerants and leak sizes can it sense?

The CLD-100 responds to a broad range of halogen-containing refrigerants—HFCs, CFCs, HCFCs and common blends—making it suitable for automotive and HVAC service. At its best sensitivity setting, it can detect leaks down to approximately 0.21 ounces per year equivalent, helping locate even small leaks before service calls escalate.

• Detects R11, R22, R134a, R404A, R410A and similar halogenated refrigerants
• Detects very small leak rates (sensitivity ≈ 0.21 oz/yr)
• Adjustable sensitivity to balance speed and selectivity

How does the probe and user interface help find leaks in tight spaces?

The CLD-100 includes a flexible 8.26-inch probe that bends into cramped engine bays, ductwork, and around insulation. The unit provides both audible tones and a visual LED indicator, plus dual-color battery status so you can prioritize troubleshooting without unexpected power loss.

• 8.26-inch flexible probe reaches awkward or confined areas
• Dual alarm feedback: sound plus visual LED
• Dual-color battery indicator helps monitor remaining power

What do I need to operate and maintain it?

The detector runs on four AAA batteries (not included) and uses a replaceable corona-style sensor; routine battery checks and keeping the probe tip clean will preserve sensitivity. Elitech also offers 24/7 US technician support by phone and email for troubleshooting and questions about use or maintenance.

• Power: 4 × AAA batteries (user-supplied)
• Simple maintenance: keep sensor tip clean and replace as needed
• 24/7 Elitech US technician support available

Who this tool is for: the Elitech CLD-100 is tailored to HVAC technicians, automotive service professionals, maintenance staff and facilities teams who need a portable, fast-reacting instrument for locating halogen-based refrigerant leaks. Its flexible probe and adjustable sensitivity make it useful for on-vehicle diagnostics, commercial refrigeration servicing, or building HVAC troubleshooting when reliable, quick detection is essential.
