Elitech CLD-100 Refrigerant Leak Detector — handheld HVAC/Automotive, 8.26-inch flexible probe & high sensitivity

The Elitech CLD-100 is a handheld refrigerant leak detector that quickly finds halogenated refrigerant leaks (CFCs, HCFCs, HFCs) with adjustable sensitivity and a flexible probe.

The CLD-100 (an upgraded version of the WJL-6000) is designed for HVAC technicians and automotive service professionals who need a reliable, portable tool to locate small refrigerant leaks. It combines a traditional corona sensor with an improved analog circuit for rapid trigger response on common refrigerants such as R11, R22, R134A, R404A and R410A, plus blends. With a short warm-up time and multiple sensitivity settings, it’s built to accelerate troubleshooting while remaining easy to use in tight spaces.

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

The detector offers a 6-second warm-up for near-instant readiness and responds rapidly when the probe encounters refrigerant vapor. Audible and visual alarms make it obvious when a leak is present, so technicians can pinpoint sources without delay.

• 6-second preheat for fast startup
• Instantaneous response to halogenated refrigerants
• Audible buzzer and visual LED alarm indicators
• Sensitivity down to 0.21 oz/year at highest setting

What kinds of refrigerant does it detect and how sensitive is it?

The CLD-100 detects a broad range of halogenated refrigerants including HFCs, CFCs, HCFCs and many blends used in HVAC and automotive systems. It features six adjustable sensitivity levels so you can trade off speed for precision depending on the inspection environment.

• Detects R11, R22, R134A, R404A, R410A and other halogenated gases
• Six sensitivity settings for coarse to fine searches
• Top sensitivity rated at about 0.21 oz/year detection capability
• Traditional corona sensor with updated analog circuitry

Can I use the CLD-100 in tight or awkward spaces?

Yes — the unit includes an approximately 8.26-inch flexible probe that bends into restricted areas commonly found behind panels, inside engine bays, and around piping. The ergonomic handheld body and clear status indicators allow one-handed operation while following the probe tip closely for precise leak localization.

• Flexible 8.26-inch probe reaches cramped spots
• Compact handheld design for single-hand control
• Audible and dual-color visual feedback while probing
• Works well around fittings, valves, and evaporator cores

What power and support options come with the detector?

The CLD-100 runs on four AAA batteries (not included), so you can source power easily in the field. Elitech provides US-based technical support via phone and email to help with setup, sensitivity adjustments, or troubleshooting.

• Powered by 4 AAA batteries for convenient replacement
• Dual-color battery indicator for quick status checks
• 24/7 US technician support by email and phone
• Simple analog controls and clear alarm indicators

Who is this for? The Elitech CLD-100 is aimed at HVAC technicians, automotive mechanics, refrigeration service providers and maintenance personnel who need a fast, affordable and portable way to locate halogen refrigerant leaks. It’s especially useful for field service work where quick warm-up, flexible probing and adjustable sensitivity reduce diagnostic time. If you want a straightforward corona-sensor detector with updated circuitry, clear alarms and broad refrigerant coverage, the CLD-100 is designed to meet those needs without excess complexity.
