HDCL is an Essential Business and will remain OPEN. Given the nature of Huston-DePue Calibration Laboratories’ (HDCL) services, many of our customers are identified as one of the 16 critical infrastructure sectors as outlined by the United States Department of Homeland Security in Therefore, HDCL has a duty to continue to provide calibration services to these “essential businesses” to the extent permitted by our available resources and federal, state and local orders.
