Buoyant weight (solids) Eudiometer, pneumatic trough (gases) Flow measurement devices (liquids) Graduated cylinder (liquids) Measuring cup (grained solids, liquids) Overflow trough (solids) Pipette (liquids) If the mass density of a solid is known, weighing allows to calculate the volume.
The name "eudiometer" comes from the Greek εὔδιος eúdios meaning clear or mild, which is the combination of the prefix eu-meaning "good", and -dios meaning "heavenly" or "of Zeus" (the god of the sky and atmosphere), with the suffix-meter meaning "measure". [8]
The two alternatives are to abbreviate as "mcg" [14] [3] or to write out "microgram" in full (see also List of abbreviations used in medical prescriptions).

Virtual reality simulators are being developed for training doctors on various endoscopy skills. [24] Disposable endoscopy. Disposable endoscopy is an emerging category of endoscopic instruments.
A multimeter (also known as a volt-ohm-milliammeter, volt-ohmmeter or VOM) [1] is a measuring instrument that can measure multiple electrical properties. [2] [3] A typical multimeter can measure voltage, resistance, and current, [4] in which case can be used as a voltmeter, ohmmeter, and ammeter.
