The CV:31A RevoTM Vibration Meter provides a simple and convenient way to measure, analyse and assess vibration data.

Capable of measuring four channels simultaneously, the CV:31A is ideal for assessing hand-arm and whole-body vibration exposure. The instrument can be used to measure whole-body vibration, as well as vibration on passenger and merchant ships.

In addition to the measurement of vibration for human exposure, the CV:31A can also measure three channels of FFT data that can be used to analyse vibration in machinery, vehicles and other vibrating structures. The CV:31A is typically supplied as part of a complete measurement kit, the CK:31HA, which includes the accessories required to carry out Hand-Arm vibration measurements, including handle mounts for the Triaxial accelerometer.

A range of accessories is available including the KD:103 Triaxial Whole Body Seat Accelerometer allowing the CV:31A to be used in a wide range of additional applications.
