The Extech EZ40 Combustible Gas Leak Detector detects the presence of combustible gas and nuisance vapors (Natural Gas, Methane, Ethane, Propane, Butane, Acetone, Alcohol, Ammonia, Steam, Gasoline, Jet Fuel, Hydrogen Sulfide, Smoke, Industrial Solvents, Lacquer Thinner, Naphtha) in concentrations as low as 10% LEL for Methane and alerts the user with audible and visual alarms.
The Extech EZ40 Combustible Gas Leak Detector is designed to detect the presence of combustible gas and nuisance vapors, such as methane, natural gas, and various solvents. It features a 16-inch flexible gooseneck for accessing difficult locations and alerts the user with both audible and visual alarms when gas concentrations reach 10% LEL for methane.
The manual details the operational procedures, including a 5-minute warm-up cycle, automatic zeroing, and leak detection techniques using the sensitivity adjustment dial. It also covers maintenance requirements, such as battery replacement with three 'C' batteries, cleaning instructions, and storage conditions to ensure reliable performance.
