Automatic Torque Tester

High-Performance Precision Measuring & Control Instrument Manufacturer

 NJY-02H Automatic Torque Tester is a dedicated device for measuring the capping and opening torque of bottled, spout, and tube packages.

The torque value for cap tightening and opening is one of the key process parameters controlled offline or online by manufacturers. Proper torque ensures safe transportation and reliable use by end consumers.

2. Applications

• Bottled containers: Measures capping/opening torque of threaded caps for food and pharmaceutical bottles.
• Tube packages: Measures capping/opening torque of threaded caps for food, pharmaceutical, and cosmetic tubes (e.g., eye drop bottles, hand cream, shoe polish).

3. Working Principle

Fix the bottle body in the lower clamping device, clamp the cap with the upper clamping device, rotate the cap at the set speed, and read the real-time torque value through the torque sensor connected to the clamping device to obtain the opening or capping force.

4. Product Features

• Class 0.5 high accuracy; multiple ranges available; automatic zero calibration at power-on.
• International brand torque sensor with imported high-speed sampling chip ensures high accuracy and repeatability.
• Automatic robotic arm capping; capping value freely adjustable; capping deviation < 0.01 N·m, much better than manual operation.
• Dual motors + cylinder drive: one motor for vertical positioning, cylinder for clamping, another motor for opening / tightening.
• Automatic pneumatic cap clamping; motor stops when cap sensor detects the cap.
• Cap detection sensor: fixture automatically lowers, positions and clamps the cap autonomously.
• 5-inch touch screen with independent menu, easy operation; displays test data and curve.
• Sensor overload protection with adjustable torque limit for safe operation.
• High torque resolution: 0.001 N·m, stable zero with minimal drift.
• Supports input of test temperature and humidity (shown on test report).
• Power-on password + 4-level authority management to prevent unauthorized operation.
• Built-in mini thermal printer for data query, statistics and printing.
• Optional professional GMP-compliant software: data traceability, multi-level authority, audit trail, electronic signature.
