Our regulators are a good example of how we develop and test our equipment before it is received by the diver. We subject all regulators to rigorous testing using an ANSTI machine before shipping. We test inhalation and exhalation resistance, work of breathing, and intermediate pressure settings on all regulators. This is our way of assuring our customers that they can rely on TUSA regulators for many years of ce certifiedenjoyable use. This quality control applies not only to regulators, but every Tabata product.
