    We use typically two monodaq ACC units for ReKi™ – broadband mass damper installations and it solves our problems.

    The small size and robustness are just want we need to do our job.

    We need to travel globally while we do vibration control work and Monodaq units can be put easily into hand luggage.

    Together with Dewesoft X3 and Monodaq units the work is easy and fun.

    We recommend Monodaq units to all professionals who need to do dynamic measurements.
