Handheld Tachometer (Revolution Counter) Overview

This handy tachometer is ideal for measuring and maintaining rotating machinery. It comes in three types: contact, non-contact, and dual-purpose, as well as an external sensor type. All types offer easy operation and highly accurate rotational speed measurement. It can be used for a variety of applications, from routine maintenance of equipment to hobby maintenance.

* Measuring with high-speed rotating equipment using a contact type device is extremely dangerous. Please use goggles or other protective gear, taking extreme caution to avoid entanglement or detachment of the contact element.
*When using reflective marks on non-contact type devices, be sure to attach them only after confirming that the rotating axis has stopped.

Measurement Example 1: Contact Type
Measurement Example 2: Non-contact type
