• 【High-Sensitivity Gas Detection】Advanced gas sensor with approximately 16 ppm sensitivity for precise halogen gas leak detection in HVAC and automotive systems.
• 【Flexible Metal Probe】418mm freely bendable metal hose probe allows easy access to tight spaces and hard-to-reach areas for comprehensive leak detection.
• 【Triple-Color Visual Alert】Dynamic three-color backlight display (green/yellow/red) provides instant visual feedback with corresponding audio alerts for different concentration levels.
• 【Dual Sensitivity Modes】Adjustable sensitivity settings with high mode (16 ppm threshold) and low mode (40 ppm threshold) for versatile detection requirements.
• 【Fast Response Time】Rapid detection with approximately 5 seconds response time for concentrations ≤20 ppm and 2 seconds for >50 ppm concentrations.
• 【One-Touch Operation】Simple one-button zeroing and error reset functions ensure quick calibration and reliable performance in the field.
• 【Auto Power Management】Intelligent 5-minute auto-shutdown feature conserves battery life when no measurement signal is detected.
