It’s recommended to re-calibrate the Prisma DI different models once every 3 years.
A calibration certificate valid for 3 years will be provided upon carrying out the re-calibration service by PrismaTibro here in Sweden.
To return back your Prisma DI instrument to us for general check-up and re-calibration, then please submit your request and we will respond in return by providing our service reference and address.
If you cannot book the freight by your own to return your Prisma DI back to us then please let us know to help you.
We are dealing with DHL and they can collect your Prisma DI and return it back to us while you will be charged for the freight cost.
