Specification :

ProvibTech’ s PT908 is ideal for overall vibration and
bearing/ gearbox measurement. The PT908 can measure
acceleration, velocity, displacement or bearing/ gearbox
condition.
A unique feature of the PT908 is its ability to pick-up the high
frequency signal from a bearing or gearbox. The vibration
trend is a good indication of bearing or gearbox running
condition.
