A sclerometer is a device used to measure the hardness of a material by determining its resistance to scratching. It is commonly used in mineralogy and material science to evaluate surface durability.
Caltech Instruments Pvt Ltd offers CES 421 – Hardness Test Pencil. This instrument has been designed for the measurement of the hardness of protective coatings. 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
The handling of the Hardness Test Pencil 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. 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:
No.1 : 0 – 3 N (blue marked)
No.2 : 0 – 10 N (red marked)
No.3 : 0 – 20 N (yellow marked)
No.4 : 0 – 40 N (white marked) (optional)
