Overview

HTPREC's Small Engine Tachometer is a compact, rugged RPM gauge designed to monitor the speed of gasoline engines across a wide range of machines. It reads up to 30,000 RPM with 1% accuracy, covering 1–8 cylinders and both 2-stroke and 4-stroke configurations. The device also tracks operating time, up to 99,999 minutes, providing insights for maintenance planning and performance checks.

Key capabilities

  • Accurate RPM measurement from 100 to 30,000 rpm with 1% precision
  • Supports engines with 1–8 cylinders, including 2-stroke and 4-stroke gasoline engines
  • Time tracking up to 99,999 minutes for maintenance timing
  • Inductive sensing or signal pickup wire for flexible installation
  • Low energy design with auto power-off when the engine is idle

Modes and operation

  • Four modes (01, 02, 03, 04) let you tailor readings; Mode 04 resets data
  • Mode 02 and Mode 03 have specific applicability: test and compare readings against actual engine speed while idling
  • Zero and reset function clears data when you need a fresh start

Practical uses

Use this compact tachometer as a maintenance reminder for chainsaws, lawn mowers, generators, ATVs, outboard motors, dirt bikes, and more. Its small form fits tight spaces on portable tools and marine vessels, while the inductive option allows quick mounting near vibration sources. The device is designed to be reliable during routine checks and on-demand performance tests.

How it helps you

By providing real-time RPM feedback and elapsed time, you can monitor operating conditions, spot anomalies, and plan service intervals. While results may vary by engine type, the tachometer offers a practical, non-invasive way to understand engine speed trends and support safer, more informed maintenance decisions.
