Instruments used in metrology
• Hygrometer - A hygrometer is an instrument used to measure the presence of water vapour in soil or in air.
• Thermometer - It is a device that is used to measure surrounding temperature.
• Barometer - A barometer is the specially designed instrument used to measure the pressure of an area.
• Ammeter- It is designed to measure electric current.
• Voltmeter - This device measures the potential difference across any two points.
• Galvanometer - It is just like ammeter but for very small values of electric current.
