Leading the 'Weigh' with Innovative Solutions and Technology®



In September 2016, OV Scale & Instruments was acquired by Kanawha Scales & Systems of Poca, WV. Kanawha Scales was founded in 1954 and has grown to become one of the preeminent industrial scale companies in the United States, with an outstanding reputation for service, quality, and safety. This will benefit our valued customers by providing them with access to Kanawha Scales’ unique product, automation and service competencies, with which we can continue to provide customized service and solutions, now with greatly enhanced capability to meet our customers’ needs.

We have always had one mission: to make life easier for our customers by taking responsibility for all of their weighing and calibration requirements.

Our ability to customize certified and non-certified scales, instruments and service programs to customers’ particular needs has made us a valuable partner to companies in a wide range of business sectors, including transportation, energy and heavy manufacturing and utilities.

Whether you need a scale or a balance, a turnkey installation, or testing services, including ISO-accredited calibrations, Kanawha Scales & Systems combines a superior level of technical expertise with personalized service that’s hard to find anywhere else.

From our beginnings in the Tri-State Area of western Pennsylvania, northern West Virginia and eastern Ohio, we’ve expanded our customer base to include companies nationwide.

We welcome the opportunity to help you automate your weighing process, calibrate or repair your railroad or truck scale, load-test your cranes, streamline your calibration management process, or do anything else related to the development, installation and maintenance of scales and balances.
