Hour meters for small engines - Accurate unresettable tot running time, which is sum run time of all engines it meters. Resettable job time can record working time of two engines separately. That means you can track how many hours of two different equipment have worked with only one timer tool. When the engine is off or not working, the tot time remains visible. Time display range of this hr meter is 0-6000h, hour counter accuracy is 0.1h

Maintenance reminder - Timing analyzer as hour/rpm checker can memorize the service time of two different engines in different time.

【 Great Digital Tach 】It used on any 2 or 4 stroke gas engine up to 16 cylinders to record the RPM ,Maximum RPM recorded for last operation activity; RPM range: 0 to 25000.the refresh rate at 0.5s or 1s .

【 Engine Tachometer rpm 】To get an accurate reading,it sparks every other revolution. But with the ignition system on these engines, every time the flywheel makes one revolution, it passes the coil and creates a spark. That would be great if this were a 2-stroke engine, Trust me, this is how you'll get an accurate reading with this tach on this type of engine.
