Endodontic File Torque Tester

Endodontic File Torque Tester is specially developed for torsional performance test of dental root canal files, including nickel-titanium rotary files and stainless steel hand files. It can accurately capture torque value, torsion angle and fracture data for quality inspection and material research of dental endodontic instruments.

Product Overview

This tester adopts high-precision torque sensor and microcomputer control system, equipped with special coaxial fixture complying with test requirements. It fixes the file tip at the specified position and applies stable torsional load to measure the maximum torsional strength and torsional fracture characteristic of root canal files. The test data can be stored, displayed and exported automatically, which is suitable for medical device factories, third-party testing laboratories and dental material research institutions.

Applicable International Standards

• ISO 3630-1:2019, Dentistry — Endodontic instruments — Part 1: General requirements

Main Features

• High-precision torque sensor, small measurement range with high resolution, suitable for micro torque test of tiny root canal files
• Forward and reverse torsion, adjustable rotation speed, conforming to ISO test speed requirement
• Special coaxial clamping fixture, can fix the file tip at 3mm position stably
• Real-time curve display of torque-angle, automatic recording of fracture torque and torsion angle
• Overload protection and stop-on-fracture function to protect sample and sensor
• Professional supporting software for data query, report export and batch test management
