About Us

Sigma Metalytics is a family owned and operated business based in Chico, California, founded in 2013. We take pride in the fact that our components are sourced from the U.S.A. and each of our units is hand-built to order right here in our Chico factory. 


We’re not a big tech company that can always overnight your order, but our engineers take the time to build, calibrate, and test each Precious Metal Verifier by hand to ensure they are the finest quality and have the highest accuracy.  


We are happy to provide technical support on the phone or over email. We can help troubleshoot unexpected readings, odd coins, problems with a device, or anything else. If the person on the phone can’t answer your questions, they will get you in touch with someone who can. 

If you have any questions or comments, please give us a call or send us an email. You’ll always speak to a real person.
