Cometech QC-310A Manual Twist Counter for Steel Wire | 2.5N–17.5N Load, LCD Display, 93×15×45 cm
- Manual twist counter for evaluating the twist properties of steel wire — measures the number of twists a steel wire can withstand before failure under a defined tensile load.
- Original load weight: 2.5N; add-on weights: 2.5N×1, 5N×1, 10N×1 — total achievable load up to 17.5N for different wire diameter test requirements.
- LCD display with button to reset to zero; manual twist operation — every 3 full turns of the specimen results in 1 recorded twist circle on the counter.
- Suitable for general twisted wire and hard wire (steel wire, cable wire) in wire manufacturing and quality control applications.

Overview
Cometech QC-310A Manual Twist Counter measures the torsional performance and twist resistance of steel wire by applying a defined axial load while the wire is twisted manually.
The main function is to test steel wire twist characteristics applicable to general twisted wire or hard wire types.
The transmission mechanism is designed so that every 3 rounds of specimen rotation equals 1 twist circle recorded on the LCD counter, ensuring accurate twist count measurement.
Key Features
- LCD display counter for accurate twist recording — zero-return button included.
- Modular weight system: 2.5N base + optional 2.5N, 5N, 10N add-on weights (up to 17.5N total).
- Manual twist operation — simple and reliable for QC and R&D wire testing workflows.
- Transmission: 3 specimen rotation rounds = 1 twist circle count.
- Suitable for: general twisted wire, hard wire, steel wire types.
