Warranty period
Every instrument we export carries a one-year warranty. The warranty period starts on the date stated on the commercial invoice.
What is covered
The warranty covers a failure of the instrument that occurs under normal use and correct operation. If the instrument fails within the warranty period, we handle it in three steps, in this order.
How a claim is handled
- Remote troubleshooting. We reply within 24 hours and work through the fault with you remotely, by email, video call or messaging. Most faults are resolved at this stage.
- Return and repair. If remote guidance does not resolve it, the instrument is returned to us for repair. Return freight is paid by us.
- Free replacement. If the instrument cannot be repaired, we replace it free of charge.
What is not covered
Failures caused by incorrect operation, or by using the instrument outside its rated specification, are not covered by the warranty.
What we need from you
- Order number and invoice date
- Model, for example HF-TC-605
- A short description of the fault and when it appeared
- Photos or a short video showing the instrument and the reading
