Portable Pencil Hardness Tester Coating Film Hardness Tester Meter 1000/750/500g

Description

The pencil hardness testing method is a simple and fast coating hardness testing method. Our set includes a complete set of tools required for testing, 13 pencils with varying hardness levels, and three weights that allow you to accurately test the hardness of the coating, helping you obtain the desired result.

Key Features

Sturdy and Durable: It is made of high-quality steel with an electroplating process, which is not easy to crack and deform, and can ensure a long service life.

Accurate Measurement: Three different weights(The tool comes with a 500g weight.) and 13 pencils(6B to 6H) can help you accurately measure the ability of the coating to resist deformation.

Thoughtful Design: The inserted pencil exhibits a precise 45° angle and three-point contact with the tested surface, making it easier to push the instrument and complete the testing process.

Details

Anti-slip Knob: It helps secure or remove the pencil while providing you with an anti-slip grip during the process.

Smooth Wheels: It can roll without lagging, making your measurement smoother and quicker.

Application

This product is suitable for laboratories, construction sites, automotive manufacturing, and factories. It can identify the hardness of the coating in any direction.

How to Use

Sharpen the pencil to expose a smooth cylindrical lead of 5-6mm, be careful not to sharpen or draw the lead.

Hold the pencil vertically at a 90 ° angle to the sandpaper (not included), move the pencil back and forth, and grind the tip flat.

Insert the pencil into the instrument placed on a horizontal fixed surface, secure it by the knob to keep the instrument level, and place the tip of the pencil on the surface of the film.

As soon as the tip of the pencil comes into contact with the coating, immediately push the test plate at a speed of 0.5-1mm/s for a distance of at least 7mm.

After 30 seconds, wipe with an eraser and observe the results. If scratches do not appear, repeat the test in the untested area and replace the pencil with a higher hardness until a scratch of 3mm or more appears. If the results are opposite, reduce the hardness of the pencil and repeat the test until scratches exceeding 3mm do not appear anymore.

The pencil hardness of the coating is represented by the hardness of the hardest pencil that does not cause scratches of 3mm or more on the coating.
