As the world's best selling apex locator, Root ZX II has set the industry standard for accuracy and patient safety. Invented in 1992, it was the first unit with the ability to work in wet canals - measurement is not affected by the presence or absence of blood, other discharges, or electrolytes. Patented technology delivers an impressive accuracy rate of 97.5%*.
As an optional upgrade, the OTR Module enables the unit to function as a low speed handpiece, apex locator, or a combination of both.
