Manufacturing, Repairing and Testing

"STB - Keeping our customers safe is our #1 priority!"

STB Electrical Test Equipment, Inc. was incorporated in January 1979 in San Leandro, CA, by my father. For over 40 years, our dedicated family and employees have worked to make the best and safest products for those of you who work with high voltage. My dad, Arnold Stewart, made sure that everyone knew that the customer and their safety came first before anything else. We still make that our number one priority and that is why we still have customers from 40 years ago.
