SDI Diagnostics, Inc. was formed in June of 1978 with a very simple philosophy: Always treat the customer as we want to be treated. This has paid dividends for the company and its many loyal customers. SDI now has representatives across the entire USA and every major medical distributor carries our products. SDI is now the largest independent supplier of spirometers and supplies. Our dedication to place the customer first coupled with innovative products will continue.
