TOPTES RT-108 Refrigerant Leak Detector – Orange handheld HVAC leak detector with halogen ionization sensor, 3 sensitivity levels

The TOPTES RT-108 is a handheld refrigerant leak detector that uses a halogen ionization sensor, adjustable sensitivity, and a flexible probe to find CFCs, HCFCs, and HFCs quickly and reliably.

Compact and purpose-built for HVAC technicians and maintenance teams, the RT-108 combines a targeted sensor with active sampling, multi-mode alerts, and a color display so you can pinpoint refrigerant leaks faster. It’s battery-powered for long inspections, includes a flexible 10" gooseneck for tight access, and offers visual, audible, and vibration alarms to suit noisy or dark job sites.

How does the RT-108 detect refrigerant leaks accurately?

The detector uses a halogen ionization sensor calibrated to react to halogenated refrigerants. An internal fan pulls air toward the sensor tip to speed sampling, while selectable sensitivity helps separate background contamination from true leaks.

• Halogen ionization sensor optimized for CFCs, HCFCs, HFCs
• Built-in fan creates negative pressure for faster response
• Three sensitivity levels (High/Medium/Low) to reduce false positives
• Manual calibration option to adapt to different environments

What alerts and display options help me work on-site?

The RT-108 offers three independent alarm types—sound, light, and vibration—so you can choose the best signal for a busy or dark location. The color screen presents immediate level feedback and a one-minute trend graph to track changes while you probe suspicious areas.

• Audible, visual, and vibration alarms—each can be enabled or muted
• Color-coded real-time display (green, orange, red) for quick interpretation
• One-minute trend graph to monitor rising or falling concentrations
• Sleep mode and color menu to preserve battery and simplify settings

How practical is the RT-108 for routine HVAC inspections?

Designed for field durability and long shifts, the RT-108 has an ergonomic non-slip housing and runs over seven hours on a single charge. A top-mounted inspection light, Type-C charging, and included carry case make the unit easy to deploy and protect between jobs.

• Ergonomic grip and industrial plastic shell for secure handling
• Rechargeable battery with 7+ hours continuous runtime
• 10-inch flexible gooseneck for access behind panels and coils
• Includes charging cable, storage case, and multilingual manual

How do I use and maintain the RT-108 for reliable results?

Basic operation is straightforward: power on, set sensitivity, and sweep the probe tip near fittings, valves, or coil seams. Routine calibration and keeping the sensor tip clean will preserve accuracy; the device also supports one-touch mute for controlled testing.

• Power on → choose sensitivity → sweep slowly around suspect areas
• Use mute button to silence alarms during precise positioning
• Perform periodic calibration and keep sensor tip free from debris
• Charge via Type-C and store in the supplied case between uses

Who is this for: The TOPTES RT-108 is aimed at HVAC technicians, building maintenance teams, and refrigeration service professionals who need a portable, sensitive tool to locate halogenated refrigerant leaks. If you inspect air conditioners, chillers, or refrigerated systems and require faster sampling, flexible reach, and customizable alerts, this detector is built to support field troubleshooting and preventative maintenance without unnecessary complexity.
