This is one of the most common questions that we ask to those who are orienting themselves to the choice of a Vickers hardness tester.
But often the answer is not so immediate, precisely because there are so many factors that must be taken into account.
We are talking about a reflection that can be analyzed in different ways:
How often would you like to use the measuring instrument?
How deep your hardness analysis have to be?
How many people will use the hardness tester?
Let’s start with order.
The manual versions are ideal for a more occasional use than their automatic counterpart, that are designed to be fully robotized.
If therefore the use is sporadic – as could be the execution of few monthly tests – certainly a manual version is better, especially if the hardness tester will be used by just one person.
Whereas, if you run many tests and the instrument is used by more than one person, whose access need to be recorded, then the robotic version is the most suitable.
However, keep in mind that the frequency of use is not the only one choice parameter that has to be taken into consideration.
You have to know that automation allows a better resolution of hardness.
For example, if you need to conduct standardized welding or Case hardness depth (CHD) measurements, a manual version would not be able to ensure the performance of the robot counterparty in terms of reproducibility, precision, speed and ease of execution.
