Introduction
A torque tester is an instrument used to measure the torque, or the rotational force, applied to an object, such as a fastener, a cap, a screw, or a rotating component, and it is used for quality control, calibration, and testing in manufacturing, assembly, laboratories, and many other applications. Torque testers measure the torque using various principles, including a torque transducer, which converts the applied torque into an electrical signal that is measured and displayed; a torque wrench with an electronic display; a torque gauge for measuring the torque applied to a handle or knob; and a torque sensor with a display unit, and they measure the static torque, the dynamic torque, the peak torque, and the torque as a function of angle, and they are available as handheld instruments and benchtop systems, with features such as digital displays, data logging, and different measurement ranges and units, such as newton-meters, foot-pounds, and inch-pounds. Torque testers are used for testing the torque required to tighten and loosen fasteners and caps, for verifying the torque settings of torque tools, for calibrating torque wrenches and screwdrivers, for testing the torque of bottle caps and closures, for testing the torque of switches and knobs, for quality control in assembly lines, for testing the performance of motors and rotating equipment, for research, and for many other applications, in the automotive, aerospace, electronics, pharmaceutical, food, and packaging industries. With their measurement of torque, torque testers are essential for quality control and calibration.

FAQ
Q1: What testing scenarios is this tester mainly applied to?
A: The torque tester is used in manufacturing, automotive, aerospace, electronics, industrial assembly, quality control and research to measure torque (rotational force) of fasteners, components and tools for calibration, quality control, testing and product development. It supports torque wrench and screwdriver calibration, fastener torque testing (bolt, screw, nut), automotive component torque testing, aerospace fastener torque verification, electronics assembly torque testing, industrial quality control torque verification, product development torque testing, and torque tool maintenance and calibration. Torque measurement is essential for ensuring proper fastener tightening, tool accuracy and product quality across manufacturing and assembly applications.
Q2: What standards does the tester comply with?
A: The torque tester follows relevant ISO, ASTM, ASME and GB/T standards for torque measurement, including ISO 6789 for torque wrenches, ASTM E2428 for torque measuring devices, ASME B107.300, and relevant GB/T standards including GB/T 15729 for torque wrenches. The hardware complies with IEC 61010 laboratory safety standards. Calibration should be traceable to national/international standards (SI N m) with certified reference torque wrenches or weights. Users should verify the specific standard for their application (tool calibration, fastener testing).
Q3: What is the warranty period for the whole tester and key components?
A: The whole torque tester is covered by a 12-month warranty. The torque sensor, electronics, display, controller and housing are covered, while fixtures, adapters, batteries and fuses are consumables or accessories. Damage from improper use, overloading (exceeding torque capacity) or unauthorized repair is excluded. Extended warranty may be available for precision models. Torque sensor may have separate overload warranty terms.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires trained personnel familiar with torque measurement, tool calibration and safety. We provide operation manuals, training and application support. Proper fixture selection, sample mounting, torque application, calibration, result reading and safety procedures are important for accurate, safe torque measurement. Overloading can permanently damage the torque sensor.
Q5: What is the typical lead-time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular calibration required? What is the recommended calibration cycle?
A: Calibration with certified reference torque wrench or weights recommended every 6-12 months for precision/regulated use, or per quality system requirements. Routine verification before each use for critical applications. Sensor condition checked (zero drift, linearity). Battery replacement when needed. Full tester calibration annually by qualified personnel for critical applications. Overload protection verified.
Q7: Are supporting consumables universal?
A: Fixtures, adapters, batteries, calibration weights and cleaning supplies are available from industrial suppliers, though fixture type should match the application. Long-term consumable cost is low.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes torque range, accuracy class, sensor type (rotary, stationary), display, data logging, connectivity, fixture types (chuck, square drive, custom), units (N m, lb-ft, lb-in, kg-cm) and accessories. Additional fixtures, adapters and accessories can be ordered separately. Custom orders extend delivery lead-time.
Q9: Does the purchase include on-site installation and commissioning service?
A: No complex installation is required for portable torque testers. Bench-top models may include installation service. The package includes the torque tester, fixtures and instruction manual. On-site training is available at additional cost for tool calibration setup.
Q10: What types of samples are compatible with this equipment?
A: The torque tester measures torque of fasteners (bolts, screws, nuts), components, tools (torque wrenches, screwdrivers) and other rotational devices within the torque range, accuracy and fixture specification. Different applications require specific fixtures: square drive for torque wrenches, chuck for screwdrivers, custom fixtures for components. The tester should not be used beyond its torque capacity (overload can damage sensor). Users should select appropriate fixture for the sample/tool, mount sample properly (secure, no slippage), apply torque smoothly and consistently (no shock loading), calibrate regularly with traceable standards, include zero check before measurement, avoid overloading (stay within 80-90% of capacity for best accuracy), report results in appropriate units (N m, lb-ft, etc.) with direction (clockwise/counterclockwise) specified, and for tool calibration, follow applicable standards (ISO 6789, ASME B107) with proper calibration points (typically 20%, 60%, 100% of range). The torque sensor should be handled carefully (avoid dropping, shock, overload). For fastener testing, use proper lubrication and thread condition per standard (torque varies with friction). For rotary sensors, ensure proper alignment (no side load). For stationary sensors, use proper mounting (secure to bench). The tester should be stored in a clean, dry environment. For data-logging models, download and back up data regularly. The torque tester should not be used with impact tools (impact can damage sensor) unless rated for impact. For critical applications, use a tester with class 0.5 or better accuracy. The tester should be re-calibrated after any overload or drop event.
