The Modal Shop

The Modal Shop is a specialist manufacturer of vibration calibration systems and precision sensing solutions, headquartered in Cincinnati, Ohio. Part of the PCB Piezotronics family under MTS Systems Corporation, the company designs and produces portable and laboratory-grade vibration calibrators, back-to-back calibration systems, and precision electrodynamic shakers used by metrology laboratories, test facilities, and calibration service providers worldwide. Their equipment conforms to ISO 16063 calibration standards and supports ISO/IEC 17025 accredited laboratory programs.

The Modal Shop's vibration calibration instruments are designed for calibrating accelerometers, velocity sensors, and force transducers with high accuracy and full traceability to national and international measurement standards. Portable models such as the 9100D and 9110D series enable field calibration of vibration sensors, allowing technicians to verify instrument performance without transporting equipment to a fixed laboratory facility.
