Cometech QC-622H Surface Hardness Abrasion Tester | Coating & Printing Wear Resistance Testing
- Reciprocating abrasion tester for evaluating surface treatment durability (paint, plating, coating, dyeing, finishing).
- Uses multiple abrasion media/heads (cotton, sandpaper, steel wool, pencil/eraser type) to simulate real wear and discoloration.
- Adjustable abrasion distance and speed with programmable cycle count and auto-stop at completion.
- Weight sets included for load control; quick clamping area for efficient specimen setup.
- Suitable for plastics, electronics, textiles, and printing-related surface testing.

Overview
The Cometech QC-622H Surface Hardness Abrasion Tester is designed to measure the durability of surface treatments such as painting, plating, coating, dyeing, and finishing.
It supports abrasion evaluation using different wear media/heads (e.g., cotton, sand paper, steel wool, eraser) to assess wear condition and surface appearance changes.
Test conditions can be configured to match different standards or internal methods, including speed, stroke (abrasion distance), abrasion head selection, load, and specimen appearance requirements.

Features & Functions
- Multi-media abrasion simulation: supports cotton, sandpaper, steel wool, and pencil/eraser-type abrasion to match real-world wear modes.
- Condition-setting flexibility: configure speed, abrasion distance (stroke), load/weights, and abrasion head type to match various requirements.
- Efficient operation: quick clamping area plus built-in stroke adjustment function (as shown in the product sheet image).
- Repeatable test runs: precise CPM speed setting, very large cycle-count range, and auto-stop when complete.
Configuration & Options
- Choose model by temperature range and environment: QC-652B (50–300°C), QC-652C (50–400°C), and corrosion versions QC-652D/E.
- MVR mechanism (for B method) is available as an optional add-on.
- High-MI material block mechanism is available to help prevent plastic flow during preheating for high-flow plastics.
