Extech VB400 Pen Vibration Meter

The VB400 is a lightweight Pen style vibration meter designed to provide simple, accurate velocity and acceleration measurements on various industrial machines. Common applications include vibration testing on motors, bearings, pumps, fans and rotating machines.

Despite being small the meter does not compromise on versatility. The VB400 is capable of measuring velocity in either cm/s, in/s or mm/s and can also measure acceleration in ft/s squared m/s squared and grams.

With clearly labelled function buttons and a single one touch mode button the tester is ready to use within seconds. The device also includes an easy to use zero out feature along with a data hold function button for temporary data recall.

Combine this with the VB400’s wide frequency range at 10 Hz to 1 KHz and a ± (5%+2 digits) basic accuracy makes it specifically suited to the industrial industry.
