Our Enthermo III ear irrigator, suitable for caloric testing, is ultra-safe thanks to its smart design. The design does not include a water tank, so it does not store stagnant water in it and thus prevents legionella bacteria growth. Water flowing through the irrigator is accurately warmed to the set temperature as it passes through the heating element. When the button on the handpiece is pressed, the water is diverted through the cannula on the handpiece. We take pride in our safe designs!
