Klein Tools Gas Tester ET120 Combustible Leak Detector (50 to 10000 ppm Methane Propane 18 Inch Gooseneck 85dB Alarm HVAC Piping Diagnostics Pouch)

Navigate Confined Pipe Joints and Isolate Vapor Escapes Instantly with Extended Gooseneck Induction Tracking Telemetry

Shop the Klein Tools ET120 combustible gas leak detector engineered to locate fuel vapor escapes in confined mechanical enclosures. This industrial sniffer maps hydrocarbons from 50 to 10,000 ppm, utilizing an 18-inch flexible gooseneck probe to navigate around appliance fittings or hidden manifold seams. Operating with dual sensitivity configurations, an automated baseline zero-calibration routine, and an 85dB ticking alert module, it isolates hazardous lines before catastrophic ignition events occur.

Best Used For:

• Residential Gas Lines: Probing structural iron threads and yellow flexible copper supply line connections for methane or propane breaches down to 50 ppm.
• Furnace Manifold Sweeps: Shifting along automated heater manifolds and burner blocks to find micro-fissures in internal infrastructure links.
• Commercial Boiler Inspections: Evaluating primary line couplings and high-volume utility control setups for localized industrial containment structural audits.

Key Performance & Safety Features

• 18-Inch Flexible Gooseneck: Extended structural arm contours cleanly around piping paths to reach tight valve clusters and deep ventilation cracks.
• Dual Threshold Sensitivity: Toggles manually between a high sensitivity track (50 to 1,000 ppm) and a low safety envelope (1,000 to 10,000 ppm).
• Multi-Sensory Alert Arrays: High-decibel 85dB acoustic buzzer matches a 5-tier red LED array to blast active hazard indicators as density spikes.
• Auto Zero Calibration: Automated balance logic runs at startup to equalize ambient atmosphere baseline counts for consistent scanning accuracy.
• Rugged Overmolded Chassis: Double-insulated slip-resistant composite frame prevents accidental tool slips inside wet utility crawlspaces.

What's Included

• ET120 Combustible Gas Leak Detector
• Protective Storage Pouch
• Four AAA Alkaline Batteries
• Instruction Manual

Technical Specifications

Pro-Tip: Always power on the sniffer in a known clean atmospheric area away from the suspected pipeline junction; this ensures the auto-calibration cycle maps a genuine zero reference baseline to maintain sensor accuracy.
