Rotaro 3.0 Tachometer

Rotaro 3.0 Handheld Tachometer

Quick rotational-speed checks in a multitude of applications

This optical/mechanical product is just as important in the implementation and day to day operations of machinery and systems as it is for maintenance. These devices are also very helpful for checking production systems as well as research and development laboratories. Within seconds you know what condition your systems are in.

Example applications

Motors, turbines and pumps; centrifugals, conveyors; paper, foil and textiles production systems; spool and transformer coiling machines; tool machines and others.

Informative LCD

The easy-to-read LCD display provides a wealth of valuable information including the measured valued, selected engineering units, as well an indication of the selected measuring mode; contact or non-contact.

Built-in memory

When making use of the built-in memory function, the maximum, minimum, average and last value is automatically stored and easily recalled to the display by pressing the MEM key.

Complete kits

Each unit is supplied with all the necessary accessories in an attractive, protective carrying case. Each attachment has been carefully designed to provide optimal mechanical stability to ensure accurate, reliable and repeatable measurements.

Auto power off function

The "auto power off" function ensures that the batteries aren't dead the next time you urgently need to use the hand-held tachometer. After 30 seconds from the last measurement, it turns off automatically.

Mode key

With the MODE key, you can select any of the following engineering units: (rpm, m/min, ft/min, in/min, ft/sec, m/sec, m, ft ,in).

Certified accuracy

Each tachometer is supplied with a Calibration Certificate validating that its operating performance meets or exceeds its published specifications.
