Scratch Needle (Stylus)
A stylus for measuring coating hardness and adhesion, and the scratch resistance of various materials.
VIDEO
Key points / procedure
Features: Available in diamond or sapphire, with a wide range of tip radii (0.001–1.0 mm).
Applications: Ideal for measuring the peel load of coating films and for continuous scratch testing.
Operation: Insert the needle into the holder hole and fix it firmly with the screw.
Ball Indenter
Suited to high-pressure point-contact testing and to clearly distinguishing differences between samples.
VIDEO
Key points / procedure
Features: A variety of ball materials and sizes are available.
Tip: After testing, rotate the ball to expose a fresh surface for reuse.
Operation: How to set the ball and fix it to the arm.
ASTM Flat Indenter
A flat indenter with a 63.5 × 63.5 mm contact face, compliant with ASTM D1894.
VIDEO
Key points / procedure
Features: Ideal for friction testing over a wide contact area.
Preparation: Adjust the specimen size to about 63.5 × 120 mm (for sheet samples).
Operation: How to fix the jig and its behavior during measurement.
30 mm Flat Indenter
A standard indenter that supports both sheet and flat-plate specimens.
VIDEO
Key points / procedure
Features: Supports wrap-fixing of sheets and double-sided-tape fixing of flat plates.
Preparation: Adjusting the specimen to about 100 mm long makes it easier to fix.
Operation: Mounting on the balance arm and the leveling procedure.
Blade Holder
Fixes wiper rubber or spatula-shaped samples at an angle close to actual use for testing.
VIDEO
Key points / procedure
Features: Can be fixed at an angle relative to the horizontal.
Operation: How to clamp and fix the sample.
Check: Leveling the balance arm using a spirit level.
Sand Eraser Holder
Fixes a cylindrical sand eraser to measure friction changes caused by wear of the specimen surface.
VIDEO
Key points / procedure
Features: Designed to hold the sand eraser securely.
Operation: Fixing the roller shaft and the setting method.
Applications: Mar evaluation of LCDs, plastics, painted surfaces, etc.
T-Peel Unit
A dedicated unit for performing T-peel tests on various tapes and adhesives.
VIDEO
Key points / procedure
Configuration: Two chucks — one on the balance-arm side and one on the moving-table side.
Important: Fixing and releasing by the orientation of the pickup knob.
Adjustment: Importance of balance-arm height and leveling.
Artificial Leather Holder
For testing that simulates environments touched by human fingers, such as smartphone screens and car interiors.
VIDEO
Key points / procedure
Features: The contact surface is rounded rather than flat (mimicking a finger).
Preparation: Cut the specimen to fit inside the holder.
Operation: Simple fixing with the screw cap.
Tack Roll Unit
Quantifies the stickiness (tack) of adhesives, flooring, cosmetics and more via the rolling resistance of a roll.
VIDEO
Key points / procedure
Features: Measurement uses the self-weight of a stainless steel (SUS304) roll.
Applications: Evaluating the aging of adhesion and residual tack.
Operation: Mounting and adjusting the whole unit.
Steel Wool Holder
Fixes steel wool, gauze, rubber and similar materials to evaluate surface wear resistance.
VIDEO
Key points / procedure
Features: Supports φ12 mm and φ27 mm contact faces.
Preparation: Can also fix irregular materials such as sponge or fiber.
Operation: Push-in setting into the holder.
45° Pencil Holder
A holder that fixes the pencil at a 45° angle, compliant with JIS K5600 (pencil scratch hardness test).
VIDEO
Key points / procedure
Features: For evaluating coating-film strength.
Operation: Accurate adjustment of pencil protrusion using a dedicated guide.
Procedure: Attach guide → insert pencil → fix → remove guide.
Peel Clip
A clip used for peel testing of adhesive tape and for evaluating coating-film adhesion.
VIDEO
Key points / procedure
Features: A spring-clip mechanism grips the edge of tape or paperboard with one touch.
Applications: Suited to tests that apply a vertical pulling force, such as 90° peel tests.
Operation: Insert into the balance-arm tip and tighten the side screw to fix.
Roller Jig
Measures the friction coefficient of cylindrical samples such as rubber or metal rollers.
VIDEO
Key points / procedure
Features: Line contact on the cylinder side prevents uneven contact for stable measurement.
Operation: Set the roller shaft in the jig groove and tighten the screw with a screwdriver.
Applications: Evaluating the slip of printer feed rollers and conveyance rollers.
