Baltimore-based Davis Calibration, a calibration services business for test and measurement equipment, was acquired for an undisclosed amount by Orlando-based Sypris Test & Measurement, the companies said Tuesday. The deal closed Dec. 31. The nearly 100-year-old Davis Calibration, which runs 29 calibration laboratories in the United States, was sold by JPB Enterprises Inc., a Columbia-based private equity firm. Davis, formerly Davis Inotek Instruments LLC, had sold off its instrument sales business in 2007, when the company was reported to have annual sales of $30 million. Sypris, also a provider of calibration services and a wholly owned subsidiary of Tektronix Inc., did not provide recent sales information.
