Sauermann Inclined Liquid Column Manometers KX 404

Sauermann Inclined Liquid Column Manometer KX 404

Product Description

The Sauermann KX 404 is a precision inclined liquid column manometer designed for measuring very low differential pressures of air and gas. With its centered zero scale, it allows for accurate positive and negative pressure readings. The instrument is equipped with an integrated spirit level for precise alignment, a sliding graduated strip for zero adjustment, and durable Altuglas construction with nickel-plated brass fittings. It is an ideal solution for HVAC, cleanroom, and industrial applications requiring highly sensitive pressure monitoring.
