Micro hardness tester is aimed to measure the hardness of an object with load no more than 1 kgf. Micro hardness test usually refers to static indentations. The indenter used can be either the Knoop elongated diamond pyramid or the Vickers diamond pyramid. Micro hardness tester has the same testing procedure with standard Vickers hardness test but that it is carried out on a microscopic scale with high accuracy instrument.
This micro hardness tester usually tests the surface which needs a metallographic finish. If you use smaller load, it will need a high surface finish. The precision microscopes which are usually utilized to the indentations measurement are equipped with magnification of x500 for +0.5 micrometers of accuracy. However, in order to obtain this accuracy, considerable experience and care are needed.
QV 2000 Micro Hardness Tester Series
The QV 2000 series micro vickers and knoop testers comes with mechanical load application in the range of HV0.01 up to HV2 (10gf to 2kgf). It is a reliable instrument for determining the hardness of a lot of products. This type of micro hardness tester is also supplied with outstanding load system which is beneficial for forcing the application in the range of 10 grams up to 2 kg without any weight changing or hassle. In addition, it is also equipped with load selector knob which can be directly applied in any global standards.
The features which are supplied to this micro hardness tester include an accurate test force, high precise measurement, great gauge reproducibility and repeatability, and also efficiency and flexibility in use. The assembly of this instrument needs to be configured to some particular requirements.
If you prefer 1 or 3 measuring objectives or 2 indenter system, you can change the measurement form Vickers to Knoop simply by touching the button. This instrument is compatible to video imaging systems, filar systems, auto measuring systems, and MS Office applications.
Odel HMV-2 Micro hardness Tester
Another option of micro hardness tester you can consider to pick is the HMV2. This instrument combines the advanced technology of precision craftsmanship for a great accurate Vickers or knoop scale micro hardness testing instrument which can measure up to .01µm.
The features offered are touchpad for easy operation, loads from 10g to 2 kg, a lot of digital functions for data reporting and digital function, NewAge C.A.M.S for complete automatic and computer control. Also, it comes to offer you a wide range of accessories and fixtures.
QV 2000-DAT series
As another alternative of micro hardness tester you can take into your consideration is QV 2000-DAT series. This DAT series comes with a Digital Electronic Eyepiece and enhanced functionality and high resolution readings. This instrument will transfer the obtained diagonal measurements to the CPU system and it is calculated to the actual Vickers or Knoop value.
Furthermore, the DAT is also supplied with more advanced display function for more convenient use. The system of this instrument is able to show the real time statistic values. This model belongs to one of the most advanced deadweight Micro Vickers system which is available today.
The features equipped to this type of micro hardness tester include the motorized turret, high resolution digital eyepiece, motorized load control, automatic measurement, statistics and conversions, XY stage with 0.01 mm resolution, and integrated high speed.
