Data integrity is the assurance of the accuracy, maintenance of and consistency of the data. The concept of data integrity has been applied for many years. However, it has become more acute recently since auditors are paying more attention to data integrity than before. The FDA, EMA and other regulatory bodies have also set new regulation guidelines that need to be adhered to.

A quick glance at a finished surface will make you think it looks perfect. However, imperfections are bound to be there, and they may come in the form of valleys and hills, varying in both spacing and height. Roughness as that is called, exists in the form of a succession of minute irregularities. This may be caused by its own finishing process, such as the utilization of a single point tool. Surface roughness tends to be both directional and uniformly spaced. If surface roughness was a result of cylindrical or straight grinding, the roughness of the surface tends to be irregularly spaced.

Accessing knowledge can never be possible without a number as well as a standard of measurement which produces the said number. It gets more interesting with the fact that both the number and the measurement cannot exist without units. This is more or less the role of metrology. It stands out not only as an individual discipline of physical sciences but also the base of daily activities. It is in fact, safe to say that people use metrology daily without realizing it. In light of this, measurement is therefore, an economic, social and scientific necessity. Understanding this makes it easy for one to understand the importance of metrology in our daily lives.

Also known by the name of paint meter, a coating thickness gauge is used for the measurement of dry film thickness. This parameter is possibly the most important one in a wide range of industrial applications, since it has a significant impact on cost, quality and coating process. These measurements can be employed to estimate the life expectancy of coating, the performance and appearance of product, and to guarantee agreement with a host of industry standards.

A majority of companies in the process industries are looking to update its calibration systems and process. There are plenty of reasons why there’s a need of upgrading a calibration system.  Updating the process basically implies work procedures and systems for managing, documenting and performing calibration of process instruments. There is an obvious reason behind any change, and most probably, it is the issues or challenges in the present way of doing things. Let us take a deeper insight into some of the common problems that may incite process changes.

It is certainly surprising that some technicians know little about the precision measurement tools they use on a daily basis. In some cases, there may be a lack of resources to give accurate descriptions about what these tools are and what they are really designed for. This lack of knowledge may lead those technicians to buy and use the wrong tools for specific jobs.
