*Your items will be calibrated and ready for dispatch within 3 working days of receipt. If your item is being returned by courier, or Thorcal’s delivery service, this transit time is not included in the 3 days. A valid purchase order or payment must be included with your items, or this could delay calibration.

Free Calibration Certificate with purchased equipment

If you buy an item through Thorcal, and we can calibrate it in-house, we'll supply it complete with a free Traceable Calibration Certificate.

Free Site Survey and Calibration Inventory

New to calibration? Our experienced survey staff will visit your site and work with you to create an inventory of equipment that requires testing. FREE if you then use Thorcal for calibrations going forward.

Audit Support over the phone

Our staff are on hand over the phone to help you locate certificates through our online certificate portal during your audit.

Free integration of your existing calibration records into our portal

Do you have existing certificates in PDF format? Integrate these into our online certificate portal, so they are organised and accessible alongside your Thorcal certificates.

Free collection and delivery locally

Our collection drivers cover the Hull, Goole, Scunthorpe, Grimsby, East Yorkshire and North Lincolnshire areas.

Free instrument adjustment

If your item is out of tolerance and adjustable, we'll adjust it for free as part of the calibration.

Managed third party repairs

Thorcal aims to calibrate as many items in-house as possible. However, some specialist items will always fall outside of our capabilities. We maintain a network of trusted partners and manufacturers, and are always happy to manage the external calibration or repair of your equipment. We'll never go ahead with any work without your express permission.
