Serving Pasadena, TX
Pasadena lies in Harris County along the Houston Ship Channel, linked by State Highway 225 and Beltway 8. Petrochemical manufacturing drives the economy: the Chevron Pasadena Refinery, Chevron Phillips Chemical's Pasadena Plastics Complex, and the INEOS phenol and cumene plant all operate here. Nearby sit the Bayport Industrial District's chemical producers, San Jacinto College, which trains process and instrumentation technicians, and Ellington Field, hosting NASA, Texas Air National Guard, and Coast Guard flight operations.
Such plants depend on gas analyzers, pressure and force gauges, torque tools, thermocouples, data loggers, and scales. Pasadena falls outside our Mid-Atlantic pickup radius, so our Gaithersburg laboratory serves Harris County remotely. Choose prepaid ship-in service or onsite calibration appointments, documented with ANAB-accredited, NIST traceable certificates.
