Founded in 1974, Quality Control Services (QCS) has been a trusted provider of precision calibration, repair, and equipment sales for over 50 years. From our headquarters in Portland, Oregon, we’ve grown into a nationally recognized name serving clients across North America.
Our facilities include an Echelon 1 Metrology Laboratory, a dedicated Thermometry Lab, and a state-of-the-art Pipette Laboratory, all staffed by experienced technicians delivering NIST-traceable calibrations. We are accredited by A2LA to ISO/IEC 17025:2017 for a wide range of services, including balances and scales, mass standards, thermometers, pipettes, ovens, refrigerators, fume hoods, pH meters, and spectrophotometers.
Our field service technicians provide on-site calibration across the Pacific Northwest and parts of California, ensuring minimal disruption to your workflow. In addition, our comprehensive in-house repair shop — strengthened by our partnership with IES Corporation — services most brands and models of the equipment we calibrate.
As a direct distributor for leading manufacturers including Sartorius, Minebea, Ohaus, AND, Setra, ThermoOrion, Cahn, YSI, Rice Lake, and Troemner, QCS also provides high-quality lab equipment backed by our technical expertise and calibration support.
