In 1949, ISSPRO Inc was founded as a service and repair shop for heavy-duty trucks and equipment instruments. By the early 1970s, ISSPRO Inc had grown into a manufacturer of custom products for OEM customers, as well as a complete instrument manufacturer for the aftermarket. In 1999 ISSPRO Inc acquired its QS-9000 and UL registration, since then we have updated our quality system to ISO 9001: 2015 & IATF 16949:2016
