E+H Metrology develops measurement systems and software for the edges of the measurable. All our experts are dedicated to high technology: the semiconductor industry, micro electronics, mechanical engineering or the ceramics industry are our customers.

Metrology is “the science of measurement, embracing both experimental and theoretical determinations at any level of uncertainty in any field of science and technology,” as defined by the International Bureau of Weights and Measures (BIPM, 2004).

Some of the most commonly used tools are gages, calipers, micrometers, and bevel protractors. Each one is useful and accurate in its own unique way. The handheld gage is one of the most commonly used measuring tools in metrology; they measure specific dimensions such as height, width, radius, thickness, and angle.

In metrology (the science of measurement), a standard (or etalon) is an object, system, or experiment that bears a defined relationship to a unit of measurement of a physical quantity. Standards are the fundamental reference for a system of weights and measures, against which all other measuring devices are compared.

These concepts apply in different degrees to metrology's three main fields: scientific metrology; applied, technical or industrial metrology, and legal metrology.

Scientific metrology ensures that units and scales are adopted effectively within an organization and throughout an economy. More importantly, it ensures that measurement standards are widely disseminated among users within an economy.

Metrology sets the framework for reliable and consistent measurements across time and space. It establishes a reference point and enables us to trust the accuracy of our measurements. Traceability is the key to ensuring the credibility of measurements.

Metrology enables us to know the accuracy of measurements and to ensure common standards are used. In science this means we know whether an experiment actually proves what it appears to prove or whether the result could be due to inaccuracy in a measurement.

What is a primary standard in metrology? ›

A primary standard in metrology is a standard that is sufficiently accurate such that it is not calibrated by or subordinate to other standards. Primary standards are defined via other quantities like length, mass and time. Primary standards are used to calibrate other standards referred to as working standards.

Metrology methodology resembles the methodology of any other scientific discipline in formulating the concepts and in the definition of the scientific understanding structure, with methods of demonstrating and developing knowledge: the gnoseological principles of metrology.

Vernier Caliper: The most basic of metrology tools, a vernier caliper is one of the least precise tools because its measured values depend heavily on how the tool is used. Different clamping pressures, for example, can result in different values.

The consensual metrological list of terms of the "International Vocabulary of Metrology (VIM)" is divided into five main headings: (1) quantities and units, (2) measurement, (3) devices for measurement, (4) properties of measuring devices, and (5) measurement standards (Etalons) [1].

In basic terms, calibration is the comparison of a measuring instrument or equipment's performance to a reference standard of known accuracy. Metrology is the science that defines and determines the applicable standards for calibration, and calibration is the practice of taking and documenting measurements.

What Is a Metrology Engineer? A metrology engineer, or metrologist, specializes in science or engineering-related measurements. Their duties may include calibrating instruments, designing new tools or systems of measurement, interpreting data, or researching the science of measuring.

Metrology, defined as the science of measurement, encompasses the controls and requirements necessary to ensure adequate measurement quality and provide measurement assurance. Calibration is an integral part of those measurement controls and is vital to ensuring the continued adequacy of MTE for its intended use.
