About MSS Automation | Industrial Automation & Test Equipment Supplier

MSS Automation is a trusted U.S. supplier of industrial automation, PLCs, HMIs, VFDs, test equipment, and MRO tools for manufacturing, utilities, and field service.

MSS Automation is an industrial automation and test equipment supplier based in San Marcos, California. We specialize in sourcing, buying, and reselling high-quality industrial automation equipment, test instruments, and electronic components at competitive bargain pricing.

We actively buy and sell on eBay and across multiple sourcing channels to locate the best deals available in the market. Our goal is to pass those savings directly to our customers through our Shopify store by offering hard-to-find, discontinued, surplus, and professional-grade industrial equipment.

All inventory is stocked in the United States and shipped directly from our warehouse for fast domestic delivery. We do not drop-ship and we do not source from overseas third-party warehouses.

We serve customers across manufacturing, utilities, automation, electrical testing, field service, laboratories, and industrial maintenance.
