Aless™ High-Precision Refrigerant Gas Leak Detector

If your air conditioner is losing cooling power… if a refrigerator system keeps needing service but nobody can locate the leak… if you’re tired of guessing around pipes, joints, valves, and tight spaces…

Then you need to know why traditional “sniff and guess” inspections miss small refrigerant leaks, and how this high-precision detector helps identify leak points faster with real-time readings, sound alerts, and visual warnings.

1. Detects Small Refrigerant Leaks With 1PPM Resolution
Tiny refrigerant leaks are often the hardest to find. They can hide around fittings, coils, valves, and narrow pipe connections, slowly reducing system efficiency while staying almost invisible during a basic inspection.

This high-precision refrigerant gas leak detector is equipped with a professional-grade sensor that measures from 0 to 1000PPM with 1PPM resolution, helping you identify even subtle changes in gas concentration.

2. Triple Alarm System Makes Leaks Hard to Miss
Many basic detectors rely on one weak signal, making it easy to overlook a leak in noisy work areas or poorly lit spaces.

This detector uses a triple alarm system: a loud buzzer, red backlight, and on-screen simulation bar. As gas concentration increases, the sound and visual indicators become more obvious, giving you fast feedback while you scan.

3. Flexible 270mm Hose Reaches Tight Pipes and Hidden Joints
Leaks rarely happen in convenient places. They often appear behind panels, inside compact appliance compartments, or around awkward pipe bends.

The 270mm flexible universal hose helps you guide the sensor into narrow areas, around corners, and near hard-to-access joints where standard handheld inspection tools may struggle.

4. Real-Time Display Helps You Inspect With More Confidence
Guesswork wastes time, especially when you’re trying to confirm whether a system is actually leaking or just performing poorly.

The HD color screen displays real-time gas data, and the detector also supports temperature display in Celsius and Fahrenheit. That makes it easier to monitor readings clearly while working through each inspection point.

5. Rechargeable Type-C Power Keeps It Ready for Repeated Use
Disposable batteries can be inconvenient when you need the tool for routine service calls, workshop use, or multiple appliance checks.

This detector includes a built-in 1000mAh rechargeable lithium battery and charges through USB Type-C. It also includes a toggleable Auto Power Off function, so you can choose whether to conserve power or keep monitoring during longer inspections.
