Precision Instruments for Pressure, Flow, Temperature and Level

The Meriam 10AA25 manometer is a versatile, economical instrument for the measurement of pressures, vacuums, or differential pressures.

The U-tube type manometer is a primary basic standard of pressure measurement. Pressure measurements are accomplished by balancing a vertical head of indicating fluid with the pressure to be measured. As there are no cams, gears, or levers to operate in the manometer, the readings obtained are always accurate.
