Testing the quality of the material is one of the most crucial things for many key industries involved in production. Hardness Tester is one of the key instruments which is used to ascertain the hardness of the material. It is a device that tests the resistivity of the material to deformation under a certain applied force. Ensuring the accuracy and authenticity of these hardness testing equipment is essential; here comes the role of Hardness Tester Calibration Services; they ensure that hardness testing instruments are providing exact reading.
In this blog, we will discuss some points that will help you to decide whether your testing equipment requires calibration.
Below are some points that indicate the need for calibration services
Significant discrepancies in measurement: Major differences in the reading of the hardness tester, like inconsistent readings for the same material and deviation from a fixed standard, strongly indicate that your hardness testing equipment needs calibration. If there is a large variation in values of hardness for any specific material and there are no external factors that can influence the reading, then your hardness tester requires calibration services.
Zero reading issue: If the equipment doesn’t show zero reading in the absence of any force applied, then it is an indication that the zero point is not exactly aligned. Due to this issue, tester provides inconsistent and incorrect results, which impact the hardness testing of the material. Zero reading problem also shows drifting in the calibration of the equipment which makes it compulsory to look for Hardness Tester Calibration Services that verify and adjust these measuring instruments to provide accurate results.
Issues in display screen: If the screen of the tester is not showing any result or displaying unclear and fluctuating measurements, then there might be an issue in the internal functioning of the instruments, which necessitates calibration of the instrument. This can be caused due to factors, like improper alignment of the instrument, damaged indenter, or any other issue but all these issues can be fixed through calibration.
Influence of Environment: Various environmental factors also play an important role in affecting the accuracy of outcomes of hardness testers. A significant variation in temperature can affect both the testing machine and the material being tested, which leads to false readings. High vibrations, dust and debris also impact the measurement of the hardness of the material. Regular calibration of hardness testing devices maintains their capability of providing precise measurement.
Conclusion: Calibration of hardness tester enables manufacturers to select the top quality material for producing goods. However, it is necessary to know when you should require Hardness Tester Calibration Services. Various factors discussed above in this blog can indicate the need for calibration of your testing equipment. So, if you require calibration services for hardness testing devices, then A. A. CALIBRATION PVT. LTD. is one of the top companies that offer precise calibration to hardness-checking instruments.
