A quadrant is a geometrical instrument that consists of a quarter of a circle or a 90-degree arc. It is used to measure angles, determine heights, and perform various mathematical and scientific calculations. Quadrants have been historically important tools in navigation, astronomy, surveying, and other fields. Key features and components of a quadrant: Arc or Scale: […]

A pyrometer is a scientific instrument used to measure the temperature of an object or a surface without making physical contact. Unlike traditional thermometers that require direct contact with the object being measured, pyrometers are designed to measure temperature based on the thermal radiation emitted by the object. Pyrometers operate on the principle of measuring the

Pyrheliometer is a scientific instrument used to measure the direct solar irradiance, which is the amount of solar energy (sunlight) received per unit area on a surface that is perpendicular to the sun’s rays. Pyrheliometers are specifically designed to measure the solar radiation that arrives at the Earth’s surface in a direct line from the

A pycnometer is a laboratory instrument used to measure the density of a liquid or a solid material. It is designed to accurately determine the mass of a substance and the volume it occupies.  Pycnometers are commonly used in scientific research, quality control, and material testing to characterize the density and specific gravity of various substances.

A polygraph, often referred to as a “lie detector,” is a scientific instrument used to measure and record physiological responses that are believed to be associated with truthfulness or deception.  Polygraph examinations are commonly used in certain legal, investigative, and employment settings to assess a person’s truthfulness or credibility based on their physiological reactions to

A photometer is a scientific instrument used to measure the intensity of light or other electromagnetic radiation. It is used to quantify the brightness or luminance of a light source or the amount of light absorbed, transmitted, or emitted by a material. Photometers are essential tools in various fields, including physics, astronomy, environmental monitoring, photography,

A periscope is an optical instrument that allows an observer to view objects or scenes that are not in direct line of sight. It typically consists of a series of mirrors or prisms arranged to reflect light and enable the viewer to see over obstacles, around corners, or in other directions without needing to physically move

An ohmmeter is a scientific instrument used to measure the electrical resistance of a component or circuit. It is a fundamental tool in electronics, electrical engineering, and other fields where the characterization of resistance is important. Ohmmeters provide a direct reading of the resistance value in ohms (Ω) without the need for complex calculations. Features and

An odometer is a device used to measure the distance traveled by a vehicle, such as an automobile, bicycle, or motorcycle. It provides a cumulative reading of the total distance covered by the vehicle over its lifetime. Odometers are typically located on the dashboard of a vehicle, where they are easily visible to the driver. Features

Nephelometer is a scientific instrument used to measure the concentration and size distribution of suspended particles in a liquid or gas by measuring the intensity of scattered light.  It is commonly used in environmental monitoring, atmospheric science, air quality assessment, and industrial processes where the presence of particles in the air or water needs to
