AUGREX Small Engine Tachometer | Digital Inductive RPM Tool for Chainsaws, Mowers, Generators

Compact, versatile RPM tool for small engines

The AUGREX Small Engine Tachometer offers a clear digital readout and a compact footprint that fits easily in a toolbox or workbench. Designed for real‑world use, it helps you monitor engine speed during startup, warm‑up, and field checks without guesswork.

This tachometer is built to work with a range of machines you rely on—from chainsaws and lawn mowers to generators, RVs, ATVs, dirt bikes, boats, and tractors. Its inductive measurement approach keeps installation simple: you can measure RPM by placing the sensor near the ignition path or clamping the wire around the spark plug cable, then observe the RPM data in real time as conditions change.

Key benefits you may notice

• Wide RPM range from 100 to 30000 RPM supports both two‑stroke and four‑stroke engines.
• Inductive measurement allows RPM reading without direct contact with the spark plug electrode.
• Clear digital readout provides quick visibility of speed changes during different operating modes.
• One‑button reset makes it easy to clear total hours and maintenance time for fresh sessions.
• Guided measurement distance (3–5 cm) helps you achieve reliable readings with minimal setup.

Easy usage in real‑world scenarios

Use it to verify engine speed after maintenance, during tuning, or while testing a new component. Its compact design remains ready for field checks in a truck bed, shop, or outdoor workspace, helping you stay on top of performance without hassle.
