Stoughton, Massachusetts — October 14, 2026 — We’re proud to celebrate an important milestone at Particles Plus: Bob Scannell’s 10-year anniversary with the company.
Over the past decade, Bob has become an integral part of Particles Plus and our Calibration Division. As our customer base and calibration volume have grown, he has continually stepped up, putting in the time and effort necessary to keep instruments moving through our facility and back into customers’ hands.
His work is a great reminder of something we take seriously at Particles Plus: keeping our customers counting particles without interruption.
Need Service or Calibration?
If your instrument is due for calibration, requires service, or needs to be returned to Particles Plus, you can start the process through our RMA Portal:

We also send annual calibration reminders, so keep an eye on your inbox as your instrument approaches its calibration date.
And remember: Particles Plus maintains a lifetime warranty on qualifying instruments as long as they are calibrated annually within the required 12-month interval.
Regular calibration not only helps maintain measurement accuracy and traceability, it also helps protect your investment for the life of the instrument.
Congratulations again to Bob on 10 years with Particles Plus, and thank you to our entire Calibration and Service team for the work they do every day to support our customers.
