RL-HM011HB Engine Tachometer & Hour Meter with Backlight
Base engine servicing on recorded running time rather than memory. The RL-HM011HB combines an hour meter and RPM display for compatible petrol-engine ignition signals. It is for equipment owners who want runtime records, service reminders and engine-speed readings on one display.
- ✅ Plan service after real running time — Set maintenance reminders alongside the accumulated engine-hour record.
- ✅ Check engine speed during a task — View RPM after selecting the firing pattern appropriate to the engine.
- ✅ Separate one job from total use — The resettable JOB counter records a period without replacing the total-hour figure.
- ✅ Read the display in dim conditions — White backlighting illuminates readings, while red flashing draws attention to configured reminders.
- ✅ Review the highest recorded speed — The MAX RPM function retains a peak reading for inspection after operation.
Keep engine hours and service intervals together
Set the appropriate engine firing pattern before using the RPM figure. The signal lead provides a one-wire pickup arrangement for compatible petrol engines; check the supplied installation instructions and engine requirements before mounting or routing it.
Use the total counter as the ongoing record and reset the JOB counter for a particular period of work. Two individual service timers let you keep different maintenance intervals, such as the tasks specified in the equipment's own service schedule.
An RPM threshold can trigger a visual alert. It is a reminder display, not an engine controller or a guarantee against damage. The replaceable CR2450 battery powers the unit, and the housing carries an IP65 rating rather than a claim of immersion resistance.

The attached signal lead provides the connection arrangement to check against your engine instructions.

Runtime, service and RPM functions share one display; set the engine firing pattern before reading speed.

Separate areas keep the current reading and running-hour information visible.

The red display illustrates an RPM threshold reminder, not an automatic engine shutdown.

The display shows RPM during running and a clock when the engine is off.

Two service timers can track different maintenance intervals from the equipment's schedule.

MAX RPM and the configured alert serve different purposes: review a peak and flag a threshold.
