OTC’s ‘QR’ Tracking system



OTC’s latest addition: Our Tracking system has given you instant access to a host of new features over the last couple of years from tracking your equipment, downloading certificates of calibration & results, invoices and service estimates plus access to previous history records. We have now gone one step further and implemented a ‘QR’ (Quick Response) barcode system.

All instruments will have a ‘QR’ barcode on the label. When you scan the barcode with your smartphone or barcode scanner, you will have instant access to the Certificates and results anywhere in the world with an internet enabled phone/connection, examples below:
