Sauermann Vertical Liquid Column Manometers LU 200
Rp123
The Sauermann LU 200 is part of the LU series of vertical liquid column manometers, designed for measuring pressure, depression, or differential pressure of air and gas. Featuring a U-shaped liquid column, it allows for consecutive measurement of positive and negative pressures with high accuracy. The instrument enables simple zero adjustment using a movable graduated slide strip and offers compatibility with two types of manometric liquids (AWS 10 or VOLT 1S), providing flexibility for fixed or portable use.
