The Oxford Dictionary defines instrumentation as "The design, construction, and provision of instruments for measurement, control, etc; the state of being equipped with or controlled by such instruments collectively."

Instrumentation is needed in our daily life. Instrumentation involved the construction of instruments for observation, monitoring or control. An instrument measures a physical parameter, such as pressure, temperature, level, distance, angle, or vibration. Instruments can be in a simple form such as a thermometer which can be read directly or can be in the form of a complex device such a spectrumanalyzer. Instrumentation is not only used in the industry or in the laboratory but is also used at homes. Examples of instruments which can be found at homes are a smoke detector or a motion detector which can detect the movement of intruders.

The advancement of instrumentation has created a big impact on our daily life. We owe much of the devices we use today to the past inventors such as the Arab physicist Ibn al-Haytham (Alhazen) who used experimentation to obtain the results in his Book of Optics (1021). He developed the modern scientific method by combining observations, experiments and rational arguments to support his theory of vision, whererays of light are emitted from objects rather than from the eyes. This modern scientific method led to the development of various instruments such as the thermometer (1539), the telescope (1609) and the marine chronometer (1759). The advancement in instrumentation has experienced a gigantic leap since then. Nowadays advance instruments can make accurate, precise, verifiable and repeatable measurements which has never been witnessed before. The revolution in instrumentation has enabled us to develop sophisticated instruments which we see today.

In order to make a major contribution to the advancement in instrumentation, PROTOM-i has embarked on extensive investigations such as in the field of process instrumentation. Its research team has developed many instruments which can benefit the society and the industry. It has also published many research papers which add valuable information to the field of instrumentation.
