OPCS is synonymous with Excellence and Professionalism. Ever since we onboarded OPCS, about 15 years ago, they have been steadfast with our calibration, services, especially emergencies, and new products, with

the utmost diligence. I would consider OPCS as one of our best vendors.

Working with OPCS has been beneficial for our company. In the past we have had older equipment that required a retrofit for us to keep using it. OPCS was able to upgrade our equipment so we could continue to use it and not have to replace it.
