• Manometers and Bourdon gauges are fundamental pressure-measuring devices. 
• They are intrinsic parts of more complex measuring instruments, such as pneumatic comparators and flow indicators. 
• It is important therefore that students fully understand their operation, characteristics and principles of calibration.
• It also includes a separate Bourdon gauge with dead-weight calibration apparatus, enabling clear observation of the Bourdon tube mechanism.
• Pressure Measurement Bench enables students to fully investigate and compare the operation and characteristics of inclined and U-tube manometers, and Bourdon-type vacuum and pressure gauges. 

The manometers and gauges unit is a framed structure with a backboard, holding a:

vertical U-tube manometer. U-tube manometer with an inclined limb. Bourdon gauge for measuring vacuums. Bourdon gauge for measuring positive pressure. syringe assembly for pressurising and reducing pressure.

The apparatus consists of two units:

A manometers and gauges unit. A Bourdon pressure gauge calibration unit.
