Control Resources Deemed Essential by Customers and the Commonwealth During Corona Pandemic

Control Resources Deemed Essential by Customers and the Commonwealth During Corona Pandemic:  As Control Resources builds product for medical laboratory test equipment, telecom equipment, products for the DOD and other medical equipment, we have been deemed essential and remain open.  To help protect our employees, CRI has instituted social distancing policies, strengthened our daily cleaning regiment and are supporting employees willing and able to work from home.  During this critical time, we ask that customers and suppliers postpone in person visits to our facilities until after this crisis has past.  We are very grateful to have such dedicated manufacturing personnel that have chosen to come to work every day to get the job done.
