Key Facts for Revision

  • SONAR (Sound Navigation and Ranging) is the instrument of finding things that are underwater.
  • Navigators usually make use of SONAR.
  • SONAR uses ultrasonic waves to detect, locate, and measure the distance of underwater objects.
  • RADAR stands for Radio Detection and Ranging. It means using radio waves to figure out the range, angle, or speed of things.
  • An Audiometer measures how loud sound is
  • An Anemometer measures wind speed and force
  • Chronometer is a very accurate clock
  • Audiophone is a type of device that helps people hear better.
  • Tacheometer calculate the distance to a target
  • Pyrometer measure high temperature. It does this by detecting the infrared or visible radiation coming from the object. Hence, called Radiation thermometers. It follows the Stefan-Boltzmann law, which states that the heat given off by something is related to its absolute temperature. It can be used to measure the temperature of the sun too.
  • A pyrheliometer and a pyranometer are both instruments used to measure solar radiation, but they measure different types of radiation.
  • A manometer is a tool that measures the pressure of liquids or gases. It uses a tube filled with liquid to measure the pressure.
  • A hygrometer is used to measure the relative humidity in the air.
  • Odometer: distance covered by motor wheels
  • Ondometer: frequency of electromagnetic waves
  • Electroencephalogram (EEG) is used in monitoring of brain.
  • A lactometer measures how dense milk is while a butyrometer measures how much fat is in milk or milk products.
  • If the mercury inside the barometer suddenly drops, that usually means a thunderstorm is coming.
  • A thermoresistor is an electronic thermometer that alters its resistance when the temperature changes.
  • The stethoscope is a tool that doctors use to listen to a patient’s heartbeat.
  • A sphygmomanometer measures blood pressure.
  • A caratometer is used to check the quality of gold.
  • A lux meter is used to measure the intensity of light.
  • Earthquakes create vibrations that can be tracked by a tool called a Seismograph.
  • In the early 1900s, Sir Jagadish Chandra Bose invented a device to measure plant growth called a Crescograph.
  • A Raingauge is used to measure rain.
  • Geiger Counter is a tool to detect radiation.
  • A phonometer is a tool used to measure how loud someone speaks.
  • A photometer is used to measure the brightness of light.
  • Theodolite is used for measuring angular distances in the vertical plane (elevation) and the horizontal plane (azimuth).
  • Polygraph is known as a lie detector.
  • A kymograph is a device that records motion or pressure as a graph over time.
  • A gyroscope is a device that measures or maintains the orientation and angular velocity of an object.
  • A carburetor is a device that mixes fuel and air in a gasoline engine to create a gas that powers a vehicle.
  • Cardiograph measure Heart movement.
  • A Fathometer is used to measure deapth of sea.
