New-in-the-package small engine tachometer/hourmeter. Global Digital Instruments brand, this inductive surface mount meter is used on gas engines. It measures up to 7,000 RPM. 1 spark=1 RPM. Also equipped with Flash Alert that flashes required maintenance at preset intervals. Self-powered, it maintains the total machine hours and will display the RPM when running. Meter is encapsulated to protect it from harsh environments, shock, and vibration. Self-powered, it is an easy 1-wire installation. All hardware is included. Will ship. Cash only, I don’t accept any payment apps. No offers, I think it is a fair price. If the ad is posted I still have it. I take down my ads as soon as items go out the gate. Thanks for looking
