Micro hardness refers to static indentions which are made with loads which do not exceed 1 kilo gram force as the intender is either the vickers diamond pyramid or the knoop elongated diamond pyramid. So these micro hardness testers specify a allowable range of loads for testing with a diamond indenter where the result indentation is very much recorded and converted into hardness value. The loads are very light which range from grams to several kilograms as these test indentations are very small, this micro hardness tester is very much useful for a variety of applications like testing of very thin materials such as foils or measuring of individual microstructure. The types of these micro hardness testers are metallographic laboratory testers which are known because of its features which are lcd screens for displaying measuring methods, also used for testing force, indentation length, hardness value and also has dwell time which shows the number of measurements. Few of other features include it is very much equipped with easy operating system, has two optical paths. These micro hardness testers are built in high speed thermal printer device and also are equipped with a fully automatic load control. Another type which is known as auto turent motorized micro hardness tester which have few configurations which includes diamond indenter and also has 3 adjustable feet and 3 clamping device.
The other type of micro hardness tester is automatic micro hardness testers which also possesses special features which gives an exact accurate result and also complies with the standards. The indents are very much precise as these are made easy and also have versatile test patterns. Also the other ones include instantaneous data review and also have multiple conversion tables. The other type of this micro hardness tester is called as model hmv 2 which combines the latest technology and also is very much known for accurate vickers as this model has various features which includes automatic turrent and automatic load change features. This particular model is equipped with complete range of fixtures and accessories.
