The ratio technique used in the instrument provides a highly accurate detection of the file’s location. Accuracy is not affected by the presence or absence of blood, other discharges, electrolytes, saline, tap water, or hydrogen peroxide.

Automatic calibration helps ensure accuracy and eliminates the effect of changes in temperature, moisture, etc. inside the canal, even during treatment.

The large color LCD screen is easy to read and provides a clear progressive display with high contrast. The action of the meter in the display corresponds exactly to the tactile sensation of using the file.

A long touch file holder is available to be used with the probe cord. It features a fork-like tip that allows the clinician to get an apex reading by simply touching the file. The file holder is 5 inches long, autoclave safe and ideal for hard-to-reach molar procedures, thus increasing access to the work area.

It is not necessary to set the device on zero before working on each individual canal.

As an optional upgrade, users may purchase the OTR Low Speed Handpiece Module. The module snaps easily onto the back of the unit and offers a unique 90° auto torque reverse and file advancement feature. OTR maintains excellent cutting efficiency with less stress on the file, reducing the possibility of breakage.
