Timorn Small Engine Tachometer & Hour Meter | Digital Inductive, IP67 Waterproof

Overview

The Timorn Small Engine Tachometer & Hour Meter is a compact digital companion built for a wide range of equipment—from dirt bikes and chainsaws to lawn mowers and generators. It uses a digital inductive sensor to read RPM in real time while the engine runs, giving you a clear, immediate view of performance without guesswork. With a robust RPM range up to 25,000 and the option to set refresh rates at 0.5 seconds or 1 second, you can choose the level of responsiveness that fits diagnostics, tuning, or field testing.

Real-time RPM and usage at a glance

Alongside RPM, the device tracks engine running time, helping you understand usage patterns and plan maintenance. The total (non-resettable) running time covers all engines it meters, while a resettable pair of hour counters lets you monitor two different machines with a single tool. The hour display spans 0–6,000 hours with 0.1-hour accuracy, providing precise usage data for scheduling service and parts replacement.

What you can monitor

• Real-time RPM readings for quick diagnostics
• Non-resettable total engine hours
• Resettable hours for two separate engines
• Programmable rev limiter and max RPM recall
• Adjustable refresh rate (0.5s or 1s)

Maintenance cues and durability

Maintenance reminders are designed to help you stay ahead: when service is due, the display can flash a red backlight and warning icon. This digital tachometer blends practical scheduling with a simple user experience, so you can focus on your tasks rather than manual logs. The device is built for rugged environments, with IP67 waterproof protection, a replaceable battery, and a memory to preserve data through power changes.

Compatibility and setup

Selectable stroke mode supports a wide range of ignition configurations, making the unit suitable for automotive, industrial, and powersport applications. It works with two-stroke and four-stroke engines and is broadly compatible with common models such as gy6 and eu2000/eu2200/eu3000 variants. Installation is straightforward: loop the sensor wire around the spark plug lead five times and secure it with the included tie. The memory persists after battery replacement, and auto sleep plus backlight options help conserve energy on longer sessions.

Bottom line

The Timorn Tachometer & Hour Meter offers a practical, real-world tool for monitoring RPM, logging engine hours, and scheduling maintenance across two engines. It emphasizes ease of use, durability, and versatility, making it a flexible addition for equipment owners who value data-driven management without overpromising results.
