With the Vernier Variable load, students can adjust the potentiometer to provide resistances between 6 and 255 Ω, allowing them to determine the optimal load on a system.

The Spirometer can be used to perform a variety of tests related to air flow and lung volume. The sensor includes a removable flow head (22 mm ID/30 mm OD) for easy cleaning and sterilization, and a differential pressure transducer.
