services Retrofit & Extensions
The pace of technological progress is breathtaking. It is simply not possible to replace equipment, systems and installations with new acquisitions at the same speed. With our service - retrofit and system extensions - we can offer a fast and cost effective service to secure your investments – for Haefely and third-party test equipment, for AC, DC or impulse voltages.
Why a retrofit? There can be a variety of reasons why an extension or retrofit is necessary. - Enter into a higher voltage class with existing equipment
- Changes of test standards
- Lack of spare parts
- Need of automated data integration into LAN, database and reporting
- Increased failure risk of aged control and measuring electronic
- Need for automated production and remote controlled test equipment
- Upgrade controls and measuring to state-of-the-art equipment
- Test bay relocatio
