The electrical voltage is recorded on paper, magnetic tape, or another recording medium.The motion of the base with respect to the mass is commonly transformed into an electrical voltage.It consists of a mass attached to a fixed base and during an earthquake, the base moves and the mass does not.The first seismograph was developed in 1890.A seismograph is an instrument used to detect and record earthquakes.Measures the relative humidity in the atmosphere. Graphically records physiological movements e.g Blood Pressure, Heartbeat. Measures the relative density of milk to determine its purity (fat content). Measures the relative density of liquids. Obtaining a magnified view of small objects.Įxamines the internal organs of the body and can be used for minor surgical procedures. Measuring very small electrical potential difference. Measures electrical activities in the brain.Īdditional Information Name of the Instrument Used for viewing objects above sea level. Recording changes, simultaneously in physiological processes such as heartbeat, blood pressure, and respiration also used as a lie detector.Ĭonverts mechanical energy into electrical energy. Measuring the strength of the electric current. The Barometric Pressure is an indicator of the weight of the column of air ranges from a historic high of 32.01 inches to an all-time low of 25.9 inches.When there is a sudden fall in the barometer, it is an indication of a storm because the atmospheric pressure decreases all of a sudden during the storm.The Barometer measures atmospheric pressure in units of measurement called atmospheres or bars.The Barometer was invented by Italian Physicist Evangelista Toricelli in 1643.Regulates temperature at a particular pointĪn electric potential difference between two points Measures and record the electrical activity of the brainĭetect the direction and range of an approaching aeroplane by means of radiowaves Traces the movement of the heart, recorded on a Cardiograph It operates only when a magnetic field is present.įorces and velocity of wind and directions It may operate with or without a magnetic field. Difference between Ammeter & Galvanometer:Īn instrument for determining the amount of current flowing in a circuit.Īn instrument for detecting the strength and direction of minor currents in a circuit.An ammeter can measure a wide range of current values because at high values only a small portion of the current is directed through the meter mechanism.Ammeter is an instrument for measuring either direct or alternating electric current, in amperes.What is the difference between a land breeze and a sea breeze?ĥ.
