How to Buy

Due to the substantial FRAUD occurring over the Internet, PayPal and credit cards' payments are no longer accepted automatically through this website. Such payments are now accepted through a special enhanced security PayPal system. We also offer additional payment options for those customers who would not like using PayPal. Ordered items are shipped only upon receiving corresponding payments from customers. Payments from international customers are accepted by Money Wiring only.

Please contact us to make a mutually acceptable payment arrangement. Note: We do not provide callback telephone services to parties located or involved in business activities outside North America. Sales of some items and services to such parties require the Canadian Export Permit. Reference Materials and Calibration Standards Canada is not in position to obtain such a Permit on behalf of said above parties. Please consider contacting Global Affairs Canada for more information.

URGENT FRAUD PREVENTION ALERT: In the event a person or an organization claims that they are our representative, distributor, or that they can act on our behalf in any way, please contact us immediately to check the validity of such a claim.


We offer the LIFETIME WARRANTY (free exchange of a product in the extremely unlikely event of a manufacturing defect) for all our products on terms described in the User Manual supplied with each product shipped to a customer. At the same time, due to a potential risk of contamination or damage of our products while in a customer's facility, in order to guarantee biological and chemical safety of our new and customers' recalibrated products shipped to customers, we do not offer a return or a refund for any of our products and services.
