Calibration and service

We recommend recalibrating the deflection indicator once every three years to maintain the functionality. We still offer recalibration and service work for Prisma DI-4C and Prisma DI-4. Unfortunately, it is not possible to calibrate or service the older model RO-3. The few cases where this is requested, we recommend investing in a new measuring device instead.

Other products

Sometimes, we are asked if we offer Pneumatic Actuators. The answer to that question is no – those are made by another manufacturer. However, in addition to Prisma DI-5C and Prisma DI-5, we also provide Prisma DI Ovality Kit – a measuring instrument for measuring ovality and wear in cylinder liners in marine engines.


Please contact us if you have any questions or concerns, and we will find a good solution together!
