The sensing mechanism of the instrument can be hair (hair hygrometer), a plate coated with carbon (electrical hygrometer), or an infrared sensor (infrared hygrometer).Ī hygrometer composed of two similar thermometers. Ceilometers can also be used to measure the aerosol concentration within the atmosphere.Ī type of evaporation gauge or evaporimeter it is a pan used in the measurement of the evaporation of water into the atmosphere over specified periods of time.Īn instrument used to measure the humidity, or amount of water vapour in the atmosphere. At the end of the day the total length of the burn or trace, less gaps, equals the duration of sunshine hours.Ī ceilometer is a device that uses a laser or other light source to determine the height of a cloud ceiling or a cloud base from the ground. When the sun is obscured, the trace is interrupted. As the earth rotates the position of the spot moves across the card. Instrument: Campbell-Stoke Sunshine RecorderĬampbell-Stokes Pattern Sunshine Recorder employs a glass sphere to focus the sun's rays to an intense spot, which will burn a mark on a curved card mounted concentrically with the sphere. The cone-shaped bag opened at both ends so that it extends horizontally as the wind blows through it and indicates the wind direction by pointing away from the wind.Ī type of barometer used to measure atmospheric pressure.Īn instrument that continuously records and provide a graphical representation of atmospheric pressure. Wind sock is commonly used at an airport or chemical plant. The other end is wide so it will catch the smallest breeze.Ī light, flexible cylinder or cone mounted on a mast to show the direction and strength of the wind. The part of the vane that turns into the wind is usually shaped like an arrow. It spins on a rod and points in the direction from which the wind blows.

The science which is dealing with measurements and their conditions is called measurement science or metrology. Even it can be defined as the accuracy of measurements. Linear Measurements: Definition, Standards, Methods & Instruments Metrology is defined as the science of measurements or the precision of measurements.
