Which type of tubing is recommended for use with the manometer to read vacuum pressure measurements?

The recommended type of tubing for use with a manometer to read vacuum pressure measurements is rigid tubing. Rigid tubing is ideal in this context because it maintains its shape and does not collapse under vacuum pressure, which is critical for accurate readings. The stability of rigid tubing ensures that the manometer can function correctly, providing consistent and reliable measurements of the vacuum pressure without the risk of deformation that could occur with flexible or more compressible tubing options. This feature is particularly important in medical environments where precise pressure readings are necessary for safe operation of equipment connected to vacuum systems.
