Elitech Refrigerant Leak Detector ILD-100H Heated-Diode Handheld with TFT Display, 0.1 oz/yr

The Elitech ILD-100H is a handheld heated-diode refrigerant leak detector engineered to find halogen-based refrigerants quickly and accurately.

Compact and purpose-built for HVAC technicians, the ILD-100H uses a heated diode sensor and a clear TFT display to locate leaks from a wide range of halogenated gases including CFCs, HCFCs, HFCs and newer blends like R1234yf. Its adjustable sensitivity, rapid response time and straightforward controls let users scan equipment, piping and fittings with confidence while monitoring battery and sensitivity status on-screen.

How fast and sensitive is the ILD-100H at finding refrigerant leaks?

The detector offers high, medium and low sensitivity settings and can detect leaks down to 0.1 oz/year at its maximum setting. Response is almost immediate, with the sensor reacting within about one second when refrigerant is present.

• Maximum sensitivity: detectable to 0.1 oz/year
• Adjustable sensitivity: High / Medium / Low
• Response time: approximately 1 second on detection
• Quick front-panel buttons to change sensitivity on the fly

Which refrigerants and gases does this detector identify?

The ILD-100H detects a broad range of halogenated refrigerants and many blends used in modern HVAC systems. It covers legacy gases and newer formulations, making it suitable for service, retrofit and leak survey tasks across different equipment types.

• Supports CFCs, HCFCs and HFCs
• Detects HFOs such as R1234yf and blends like AZ-50, HP62, MP39
• Works with commonly used refrigerants: R11, R22, R404A, R410A, R600a and others
• Responsive to mixed and blended halogenated refrigerants

What features help technicians use it effectively on the job?

The ILD-100H pairs a heated diode sensor with a TFT screen that displays sensitivity, leak alerts and battery life for faster decision-making. Ergonomic controls let you mute the buzzer or change sensitivity instantly without interrupting inspections.

• TFT screen shows real-time sensitivity, alerts and battery status
• Two front buttons for quick sensitivity changes and buzzer mute
• Heated diode sensor for improved detection accuracy versus older sensor types
• Lightweight handheld body for easy maneuvering around coils and fittings

How reliable and serviceable is the Elitech detector?

Elitech provides one-year warranty coverage and offers customer support to help with troubleshooting and parts. The heated diode sensor is designed for stable operation across a range of halogenated refrigerants, reducing false readings common with older sensor technologies.

• One-year warranty included
• 24/7 customer service availability advertised by Elitech
• Durable heated diode sensor minimizes cross-sensitivity issues
• Simple controls and clear display reduce operator error

Who is this for: The Elitech ILD-100H is aimed at HVAC technicians, service contractors and facilities maintenance professionals who need a portable, reliable way to find halogen refrigerant leaks across residential and commercial equipment. It’s particularly useful for users who require fast response, adjustable sensitivity and clear on-device status indicators while inspecting lines, valves, fittings and coil assemblies.
