Historically, the definition of a scientific instrument has varied, based on usage, laws, and historical time period. [1] [2] [3] Before the mid-nineteenth century such tools were referred to as "natural philosophical" or "philosophical" apparatus and instruments, and older tools from antiquity to the Middle Ages (such as the astrolabe and pendulum clock) defy a more modern definition of "a ...
A mobile laboratory is a laboratory that is either fully housed within or transported by a vehicle such as a converted bus, RV, or tractor-trailer. [1] [2] Such vehicles can serve a variety of functions, including: Science education; Science research; Air, water, and soil analysis and monitoring; Biosafety
This includes mostly instruments which measure macroscopic properties of matter: In the fields of solid-state physics; in condensed matter physics which considers solids, liquids, and in-betweens exhibiting for example viscoelastic behavior; and furthermore, in fluid mechanics, where liquids, gases, plasmas, and in-betweens like supercritical ...
Name Purpose Ammeter (Ampermeter) : Measures current Capacitance meter: Measures the capacitance component Current clamp: Measures current without physical connection
electrical equipment Apparatus for generation, transmission or utilization of electric power. electrical grid A geographically distributed system to connect source and users of electric power. electrical impedance That property of a circuit that resists the passage of electric current, usually in the context of alternating current.

A clamp holder or clamp fastener is a piece of laboratory apparatus that is used to secure laboratory clamps, such as extension-type utility clamps, or other attachments to a retort stand or lab frame. [1] The material can be made up of brass, cast iron, stainless steel, aluminium or nickel-plated zinc. [2]
Relation to Physics [ edit ] The VSM relies on Faraday's law of induction , with the detection of the emf given by ε = N d d t ( B A c o s ϑ ) {\displaystyle \varepsilon =N{d \over dt}(BAcos\vartheta )} , [ 7 ] where N is the number of wire turns, A is the area, and ϑ {\displaystyle \vartheta } the angle between the normal of the coil and ...
