HIGH PRECISION TACHOMETERS (RPM GAUGE)

Measure rotational speed with accuracy

Tachometersalso known as revolution-counters, rev-counters, RPM gauges, or tachos—are essential instruments for accurately measuring the rotational speed of moving components. Whether you're monitoring machine discs, drive belts, motors, or other rotating parts, our tachometers deliver fast, reliable readings in revolutions per minute (RPM) on a clear digital display.


Versatile Measurement Modes: Contact & Non-Contact (Optical)

Our advanced tachometers are designed to suit a wide range of industrial, automotive, and mechanical applications across Ireland. Key features include:


  • Direct Contact Measurement: Use the built-in probe sensor to measure rotational speed by making direct contact with the object.
  • Optical (Non-Contact) Mode: Enables fast, safe RPM measurements from a distance, ideal for moving parts or hard-to-reach locations.
  • Longer Measurement Distances: Enhanced optical sensitivity ensures accurate readings even from greater distances.

Reliable Performance – Nationwide Delivery in Ireland
