Vibration measurement services

Custom services on demand

My offer: Gaining quickly your needed measurement data by expertise and innovative measurement technology

- global on-site service -

Vibrations affect the durability, comfort and functional performance of products and processes. With adequate measuring technology and enough "manpower", vibration phenomena can be recorded and structural improvements can be derived from measurement data analysis. When your own resources or measuring equipment may not be sufficient to cope with the upcoming vibration measurements challenges.

In this case, I am happy to assist you as a competent service provider with the latest vibration measurement technology and expertise and help you to implement the desired measurement services as soon as possible. Efficient and customer-oriented vibration measurements services - paired with conventional and modern optical measurement technology (such as a single-point laser vibrometer, scanning laser vibrometer) - are my strengths.
