Chronometer is an instrument used to measure time. It’s a special and quite expensive device or a watch equipped with many features that measures time more precisely and accurately. It is used in for navigation and for scientific purposes.  Read More →

Chronograph is an instrument use to record the moment of an event like stopwatch. It measures the interval and tells you how long the event last. Chronograph tells you all this graphically.  Read More →

Coronagraph is an instrument used for viewing corona of the sun. Corona is the outermost part of the sun. Due to intense light rays, one cannot be able to see corona, thereby we use coronagraph, which hide the direct light from the sun, and allows you to observe the outer part. It has wide use in finding... readmore

Coulombmeter is an instrument used to measure Electric charge. Coulomb is the SI unit of charge. It is also termed as voltmeter that is used to calculate the potential difference across the capacitor. It is available in both analog and digital forms.  Read More →

Alkalimeter is an instrument used to measure the strength of alkaline. Alkalimeter determines the uninflected use of acid-base titration for the assiduity of an alkali or basic substance. It is said to be base which get dissolves in water. Any solution, which has base/alkali in it, has pH value always... readmore

Alcoholometer is an instrument used to measure the content or proportion of alcohol in solutions by volume, in ethanol/water mixtures. There should be no other mixture in a sample else the result will be incorrect. The most common types of alcoholmeter are weight %, volume % and Cartier. It is also called... readmore

Aerometer is an instrument used to measure weight of air, mass or density of gas and liquid. They are not complicated instruments and are also used in the aircrafts. One can understand the basic function of aerometer by understanding the basic law of Archimedes. Simpler aerometer is used to measure only... readmore

Actinometer is an instrument used to measure the incident radiation. It measures the electromagnetic rays coming from sun to earth by photochemical effect by determining the number of photons per unit time.  Read More →

Ammeter is an electronic component used to measure the electrical current. The current is basically measured in amperes (A) so the name of its instrument is after its name. There are different types of ammeters like digital and analog, but the purpose is to check how much the current is flowing in a... readmore

Acidimeter is an instrument used for measuring concentration, specific gravity or amount of an acid in any solution. It tells you the pH of any solution like how much it is either acidic or alkali.  Read More →
