    Tachometers/Hour Meters for Gas Powered Engines

    Image of Product. Front orientation. Tachometers. Tachometers/Hour Meters for Gas Powered Engines.
    Continuously measure the speed and running time of your engine to monitor its performance and detect mechanical issues early. These meters can be programmed based on engine run time to light up for maintenance reminders, such as oil changes, filter replacements, and inspections. Wrap the signal wire four to five times around your spark plug to secure it in place. They’re battery powered, so they will start showing readings as soon as you turn on the engine. It adjusts to nine different engine types for accurate readings.
    IP67 Enclosure Rating—They’re rated IP67, so they won’t get damaged from dust and water.
