Sphygmomanometer is a medical device used to measure blood pressure. It typically consists of an inflatable cuff to collapse and then release the artery under the cuff in a controlled manner, and a mercury or aneroid manometer to measure the pressure.  The term “sphygmomanometer” is derived from the Greek words “sphygmos” (pulse) and “manometer” (pressure […]

A spherometer is a scientific instrument used to measure the curvature or radius of curvature of a spherical surface. It is a specialized tool often used in optics, astronomy, and other fields where precise measurements of spherical surfaces are required. Spherometers are particularly useful for testing and verifying the shape of lenses, mirrors, and other

A spectrometer is a scientific instrument used to measure and analyze the properties of light or other electromagnetic radiation. It separates light into its individual wavelengths or frequencies, allowing researchers to study the unique spectral patterns associated with different sources of light or materials. Spectrometers are used in various fields of science and industry to gather

What is Spectroscope? A spectroscope is a scientific instrument used to analyze and study the properties of light. It separates light into its individual components, or wavelengths, allowing researchers to observe the unique spectral patterns associated with different light sources. Spectroscopes are widely used in various fields, including physics, chemistry, astronomy, and materials science, to

Sonar (Sound Navigation and Ranging) is a technology that uses sound waves to detect and locate objects underwater. It works on the principle of sending out sound waves and analyzing the echoes that bounce back from objects in the water. Sonar is widely used in marine navigation, underwater exploration, fisheries, military operations, and scientific research.

Sextant is a navigational instrument used to measure the angle between two objects, typically the horizon and a celestial body such as the sun, moon, or stars.  It is an essential tool for celestial navigation, allowing sailors, aviators, and adventurers to determine their position on the Earth’s surface based on celestial observations. Sextants have been

Salinometer is a scientific instrument used to measure the salinity of a liquid, typically water. Salinity refers to the concentration of dissolved salts, primarily sodium chloride (table salt), in a solution. Salinometers are widely used in oceanography, marine biology, environmental monitoring, and various industrial applications where accurate measurement of salinity is important. Key features and

A refractometer is a scientific instrument used to measure the refractive index of a substance, typically a liquid. The refractive index is a measure of how much light is bent or “refracted” as it passes through a material, compared to its speed in a vacuum. Refractometers are widely used in various industries, including food and

Radio Micrometer is also known as a “Radio Micrometer Interferometer” or “Radio Micrometer Radiometer.” This is a type of instrument used in radio astronomy to precisely measure the positions of celestial radio sources and to study their emission properties. Radio micrometers use interferometric techniques to achieve high angular resolution in radio observations. They consist of

Radar (Radio Detection and Ranging) is a technology that uses radio waves to detect and locate objects in the surrounding environment. It works by emitting radio frequency (RF) signals and analyzing the reflections or echoes of those signals when they encounter objects.  Radar is widely used in various applications for navigation, surveillance, remote sensing, weather monitoring,
