Instruments for measuring or checking pressure of liquids or gases: Bourdon gauges, manometers, pressure transmitters and vacuum gauges.

Provide pressure range, accuracy class and connection thread; ship oil-filled gauges upright and sealed to avoid leaks. Measuring and analytical instruments are precision goods: provide calibration certificates traceable to national standards, accuracy specifications and operating manuals, and pack in foam-lined cases with desiccant to protect sensors and optics from shock and humidity.
