Returns & Exchanges
Effective July 22, 2026
We want every instrument we sell to be the right one for your application. If something is not, here is how returns and exchanges work at Valley Instrument Service. The short version: contact us first, and we will take care of you the same way we have since 1971.
Standard returns
Unused products in their original packaging, with all accessories and documentation, may be returned within 30 days of receipt. Before shipping anything back, contact us so we can confirm the return and give you shipping instructions: call (661) 327-8681 or email sales@valleyinstrument.com. Returns are inspected on arrival; refunds issue to the original payment method or as account credit.
Restocking fee
Non-defective returns are subject to a 25% restocking fee. The fee is waived when the return results from our error. Return shipping is the customer's responsibility except for defective items or our error.
Non-returnable items
Custom-manufactured products (including custom thermocouples, RTDs, and configured-to-order items), special-order items, opened software, calibration services already performed, and consumables such as gas sensors and calibration gas are not returnable.
Defective items and warranty
Products that arrive defective or fail within the manufacturer's warranty period are handled under that warranty. Contact us within 7 days of receipt for items that arrive dead on arrival, and we will manage the replacement or repair with the manufacturer on your behalf.
Exchanges
We gladly exchange for a different model or configuration. Contact us the same way as for a return, and our team will help confirm the replacement fits your application before it ships.
