Overview
The TRUIT TR 5105/A Benchtop Electric Pencil hardness tester is a professional device for Coating paints film hardness testing with a standard 45 degree test angle for accurate measurement of film Hardness. Equipped with 500g, 750g and 1000g test load options, the device has a reset function and comes with a set of Chinese standard pencils. It is widely used in the Coating, paints and coatings industries to provide reliable Hardness data for quality control and product evaluation.
Features
1. Adopt standard 45 degree test angle to ensure measurement accuracy
2. Equipped with a variety of test load options (500g, 750g, 1000g)
3. With reset function, it is convenient to quickly reset the test device
4. Comes with a set of Chinese standard pencils (1 each of 13 6B~ 6H)
5. Test platform traverse speed 0~ 300mm/min adjustable
6. The travel distance is adjustable from 0 to 90mm
Principle
The instrument is mainly composed of a pencil holder and a test bench. The pencil holder and the column form a four-bar structure, which ensures that the weight of the weight acts vertically on the intersection of the pencil lead and the test bench, and keeps the pencil and the test bench at an angle of 45 °. The test bench can move horizontally and vertically, use it to fix the Coating sample, and make the sample swipe in the direction of scratch, and the pencil draws the corresponding track on the test piece. Use different pencils to draw different marks, according to which the Hardness value of the film can be determined.
Applications
Coatings, paints, coatings
Steps
1. Fixed Coating Sample on Test Bench
2. Choose the appropriate load weight (500g, 750g or 1000g)
3. Install the corresponding Hardness pencil
4. Adjust the traverse speed and travel distance of the test platform
5. Start the device to swipe the sample in the direction of scratch
6. Observe the trajectory drawn by the pencil on the test piece
7. Hardness pencils, repeability test
8. Determine the film Hardness value according to the scratch result
