Product Description

Itokii Vibration Meters use an accelerometer to measure g-force on 3 axis and then determine speed and frequency. They can be set to only capture when a vibration occurs and sleep when no vibrations are present, or they can be set to measure at a given assessment interval regardless of whether a vibration has occurred. If set to always measure, the sensitivity can be further adjusted to filter out noise. The Vibration Meter will also report the duty cycle, or how long the sensor was measuring vibrations throughout the heartbeat.

Itokii Industrial Sensors come in an IP65, NEMA 4X, CE rated, sealed, and weatherproof enclosure. They are powered by a single, replaceable, Industrial grade 3.6 V battery (included).

An optional solar powered version is also available. The solar powered version includes a Lithium Iron Phosphate rechargeable battery in conjunction with a solar power cell to keep the battery charged and at optimal capacity. If there is no light present at the solar cell, the battery alone could continue to power the sensor for up to 5 years.

Product Features

  • Reports data as speed (mm/s) and frequency (Hz) on all three axes, and how long the sensor was measuring during the interval.
  • Adjustable measurement methods: Peak acceleration RMS, peak velocity RMS, and true RMS.
  • Free Itokii basic online wireless sensor monitoring and notification system to configure sensors, view data and set alerts via SMS text and email.


  * Actual range may vary depending on environment.
** Battery life is determined by sensor reporting frequency and other variables.
