REAL ESTATE

Horiba Instruments Inc., which says it’s the largest maker of auto emission-control equipment in the world, bought an industrial building in the Irvine Business Complex near John Wayne Airport for its U.S. headquarters.

Horiba paid $2.5 million for the 40,000-square-foot building, which sits on 2.3 acres on Armstrong Avenue. The company plans to renovate the building and move in during the spring. The seller was Parker Hannifin Corp.

Japanese-owned Horiba is consolidating two other buildings it now occupies in Irvine, said the company’s broker, the Seeley Co. Horiba sells to auto makers who use its large measuring devices in their manufacturing plants.
