Dewar Service Department

Dewar has a dedicated service team to repair and upgrade any Dewar manufactured products.

When sending back your Dewar product for repair/ upgrade/annual test certification, please print and fill in the “customer authorisation form”  and send back with your NST™ or email to sales@dewar.com.au.

If your NST™ requires a repair, the team will contact you prior to repairing with a quote. Repairs will not go ahead until the quote has been accepted. 

Dewar’s standard turnaround time for re-certified NST™ are 5 business days, however this is typically done within 2-3 working days. If you require your NST™ back urgently, please advise and we will endeavour to get this done ASAP. 

If we receive large batches of NST™ for re-certification, these may take longer. 

NOTE: Dewar Electronics is the only company that can perform accurate upgrades and annual checks on the Dewar NST™ as a specific software is needed to achieve this. Dewar has not released this software to any other company to perform upgrades and checks. 

Please visit the NST™ page for more information on the unit and accessories.
