TOPTES refrigerant leak detector RT-108 – halogen sensor, 10.2in gooseneck, 3 sensitivity levels (Blue)

Designed for HVAC technicians and maintenance teams, the RT-108 combines a sensitive halogen-specific sensor, a 10.2-inch flexible gooseneck, and a color TFT display to make leak tracing faster and easier in tight or noisy environments. Lightweight and battery powered, it delivers long runtime and selectable alarm types so you can adapt detection to the job site.

How fast and sensitive is the RT-108 at finding refrigerant leaks?

The RT-108 responds in under one second thanks to its halogen ionization sensor and a rear-mounted fan that pulls gas samples toward the tip. Sensitivity is adjustable across three levels, enabling both coarse scans and fine pinpointing of small leaks.

• Response time: <0.5 seconds typical
• Sensitivity range: 0.1–1 g/yr
• Sensor type: halogen ionization, optimized for CFCs, HCFCs, HFCs
• Replaceable sensor module with cumulative 50-hour operating recommendation

What alarms and indications help me locate leaks in noisy or dim conditions?

RT-108 offers a triple alert system—audible, visual and vibration—so you can detect leaks even when audio cues are hard to hear. The large color TFT screen shows a funnel-style level chart, trend graph and indicator lights for instant visual feedback.

• Audible alert: 65–75 dB ticking tone
• Visual modes: curved funnel chart, 1-minute trend graph, indicator lights
• Vibration mode for noisy environments or hands-on inspections
• Independent enable/disable for each alarm type

How long will the detector run between charges and how long to recharge?

A built-in 2500 mAh lithium battery powers extended inspections without frequent recharging. Charging uses a USB-C input; a full charge typically takes around five hours and supports seven to eight hours of continuous operation.

• Battery: 2500 mAh, 3.7 V rechargeable
• Operating time: ≥7–8 hours depending on settings
• Charge time: approximately 5 hours (5V=2A input)
• Convenient Type-C charging cable included

What practical features help with real-world HVAC inspections?

Ergonomic housing, a long flexible probe and a compact weight make the RT-108 comfortable for sustained use and access to tight areas. The unit includes one-touch mute, manual calibration and a top-mounted inspection light to simplify workflows on-site.

• Probe: 10.2-inch (approx. 26 cm) flexible gooseneck for hard-to-reach spots
• Weight: 277 g (9.77 oz) for low fatigue during inspections
• Rugged engineering-plastic housing for durable field use
• Package: detector, Type-C charging cable, storage case, user manual

Who this product is for: technicians, facility maintenance staff, and HVAC professionals who need a sensitive, portable refrigerant leak detector with clear visual feedback and multiple alarm options. The RT-108 is particularly useful when locating halogenated refrigerants in confined spaces or noisy job sites, and it suits users who require a replaceable sensor and long battery life for extended inspection rounds.
