Sclerometer Hardness Tester

Caltech India is the manufacturer and supplier of CES 421 Sclerometer Hardness Tester. Hardness Test Pen is a pocket instrument to measures the hardness of a coating by moving a Tungsten Carbide Tip over the coating with a predetermined force. The degree of hardness of paint films, plastic, coatings, etc. can be accurately measured and recorded with the Sclerometer Hardness Tester. No matter whether on a level or curved surface, small or large. The instrument is always ready for use and, because of it’s small size easy transportable, an asset which will be appreciated by all concerned with hardness tests. It is also called as sclerometer, also known as the Turner-sclerometer. It Is used to accurately measure and record the hardness of various materials (such as coatings, plastic, wood or metal surface hardness. This is also used by metallurgists, material scientists and mineralogists to measure the scratch hardness of materials.

The handling of the Sclerometer Hardness Pen is extremely simple. The estimated or known spring tension is set with the help of the slider. Holding the instrument upright and placing its point on the test surface one draws a 5 to 10 mm long line at a rate of approximately 10 mm/sec. A visual mark on the surface after use of the Hardness Pen indicates a fail of the surface hardness or wear or scratch resistance. The pen can be used on flat and curved surfaces. The laser-engraved scale is clearly visible on the grey background The stylus should produce a scratch which is just visible with the naked eye. If the spring pressure is too high, the scratch is clearly visible; if too low, no scratch appears. The applied pressure, fixed by locking the slider, is marked in Newtons.

Features:

• The measured surface can be flat or curved.
• Not limited by area size.
• Easy to operate, stable performance.
• Easy to carry and other characteristics.

Three scales are engraved into the test pencil for the three pressure ranges:

1. No.1 : 0 – 3 N (blue marked)
2. No.2 : 0 – 10 N (red marked)
3. No.3 : 0 – 20 N (yellow marked)
4. No.4 : 0 – 40 N (white marked) (optional)

Each hardness pen is in accordance to DIN 55656. Additionally, results can be obtained equal to: ISO 1518; AS 3894.4; EN 438-2, SIS 184188, and corporate standards like Bosch, Volvo, Opel and Van Laa
