The HT Series of Handheld Tachometers are ideal for the measurement and maintenance of rotation machineries.

We provide four types of tachometer (contact, non-contact, contact and non-contact, and external sensor) and each model can be easily operated to accurately measure the rotation precisely. They are used in the various applications for periodic maintenance of mechanical equipment and general purpose rotational speed measurements.

A wide range of accessories are also available to support the instruments.

  •  Compact, accurate handheld tachometers
  •  Available as contact, non-contact and external sensors versions
