A scientific instrument is, broadly speaking, a device or tool used for scientific purposes, including the study of both natural phenomena and theoretical research. Historically, the definition of a scientific instrument has varied, based on usage, laws, and historical time period. Instrument makers designed, constructed, and refined instruments for specific purposes, but if demand was sufficient, an instrument would go into production as a commercial product. In a description of the use of the eudiometer by Jan Ingenhousz to show photosynthesis , a biographer observed, "The history of the use and evolution of this instrument helps to show that science is not just a theoretical endeavor but equally an activity grounded on an instrumental basis, which is a cocktail of instruments and techniques wrapped in a social setting within a community of practitioners. The eudiometer has been shown to be one of the elements in this mix that kept a whole community of researchers together, even while they were at odds about the significance and the proper use of the thing. By World War II, the demand for improved analyses of wartime products such as medicines, fuels, and weaponized agents pushed instrumentation to new heights. Scientific instruments vary greatly in size, shape, purpose, complication and complexity.

Scientific instrument

Scientific instruments are part of laboratory equipment, but are considered more sophisticated and more specialized than other measuring instruments as scales, meter sticks, chronometers, thermometers or even power or waveform generators. This piece of writing is truly a pleasant one it helps new web visitors, who are wishing in favor of blogging. Your email address will not be published.

Microphone Converts sound waves into electrical vibrations Microscope To obtain a magnified view of small objects Nephetometer Measures the scattering of light by particles suspended in a liquid Ohmmeter To measure electrical resistance in ohms Ondometer Measures the frequency of electromagnetic waves, especially in the radio- frequency band. Periscope To view objects above sea level used in submarines Photometer Compares the luminous intensity of the source of light.

It is also known as altitude meter. It is used to measure the altitude or distance of an object above a fixed level such as the earth' surface, water surface, etc. For example, it can measure the altitude of an airplane, spacecraft, etc. Pressure altimeter or aneroid barometer : It measures the location's altitude or distance above a fixed surface by calculating the air pressure of the object that can be an airplane or a hot air balloon or any other object flying in the sky.

Scientific instruments are devices used for scientific purposes that are for indicating, measuring and recording physical quantities. They are used for both natural phenomena and theoretical research. Let us tell you that instruments in the digital era mainly depends upon the integration with computers to improve and simplify control and extend instrumental functions, conditions, adjusting parameters, data sampling, etc. Here we are giving list of various scientific instruments, their uses and name of the inventors which will be helpful in several competitive examination preparations.
