GENERAL QUESTIONS
Does Onda have ISO certification?
We are currently working towards ISO 17025 and 9001 certification, but have not yet completed the process.
Do Onda calibrations have NIST traceability?
Unfortunately, NIST no longer provides traceability for ultrasonic field measurements. Onda's calibrations are accomplished through the use of reference equipment calibrated at a National Laboratory such as National Physical Laboratory (NPL) in the UK or Physikalisch-Technische Bundesanstalt (PTB) in Germany. The particular reference equipment and national laboratory used for any calibration is referenced on the calibration certificate.
Why should I use Onda for a calibration instead of going to a National Laboratory directly?
Onda will perform a free evaluation on any Onda, SEA, or NTR equipment first, before commencing with the calibration. Because we are the manufacturer, we can tell you if there are any problems, and in that event can give you the option of foregoing the costly calibration. Depending on the status of the warranty and age of the device, you may also be able to obtain a replacement at a discount (contact Onda for details).
Over what frequency range do you calibrate your hydrophones?
A 1-20 MHz calibration is offered as standard on all of our hydrophones. Our calibration capabilities extend from 250KHz to 60 MHz.
