Sauermann Vertical Liquid Column Manometers LU 400

Sauermann Vertical Liquid Column Manometer LU 400

Product Description

The Sauermann LU 400 is the largest model in the LU series of vertical liquid column manometers, developed for accurate measurement of pressure, depression, or differential pressure in air and gas systems. With its U-shaped liquid column design, it allows consecutive measurement of positive and negative pressures. The LU 400 is built with a transparent Altuglas body for durability and clear readability, and it offers zero adjustment by means of a movable graduated slide strip. Compatible with AWS 10 or VOLT 1S manometric liquids, the LU 400 is suitable for both fixed and portable applications.
