When books are not enough for all information, engineering students try internet blogs to update themselves. We provide daily analytical instruments topic related information & ideas on our blogs.
What is meant by Conductivity? How is conductivity measured? Units of Conductivity Conductivity Meter Cell constant x conductance = Conductivity. Note that the current source is changed to make the measured potential (V) and reference potential (Er) identical (about 200 mV apart). Conductivity Measurement principles Conductive principle A cell having two metal or …
Gas Detection Gas detection works in tandem with other fire detection systems, like smoke, heat, and flame detectors. List few examples of Gas installation unit How to connect a gas detector? Three alternative connections can be made between gas detectors in order to deliver various levels of information. 1. Stand Alone – The detector has …
What is Intrinsic Safety? Intrinsic safety (IS) It is an idea of a shielding or safeguarding technique for the secure operation of electrical equipment located in hazardous areas by avoiding or reducing the source of available electrical and thermal energy to cause ignition. It is a low-energy signalling technique to prevent firing events by verifying …

Megger: A Megger is a firm that manufactures megohmmeters, a device used to measure insulators’ level of resistance. Because of the numerous industrial applications, it is a very significant instrument. It offers a very high DC voltage for the resistance measurement. It is a portable instrument that is also known as a megohmmeter. It can …
A wattmeter is a device that measures the amount of electricity delivered to or generated by an electrical circuit. These instruments are frequently employed for the distribution and transmission of electric power, as well as for protection. A wattmeter typically consists of two coils: Current coil and Potential coil What is Current Coil? A coil, …
Ammeter: The term “ammeter” refers to an instrument or device used to measure current. The current is measured in amperes. As a result, this instrument is known as an ammeter or ampere metre and measures current flow in amperes. Although this device’s internal resistance is “0,” it still has some internal resistance. Depending on the …
Clamp Meter: A clamp meters is an instrument that measures current in an effective, practical, and secure way without the use of test leads. It was aware that the current flowing through a conductor can produce a magnetic field. Therefore, the magnetic field can be detected using this instrument, which will then give the reading …
What is Voltmeter? The device used to measure the electric potential difference between two points in an electric circuit is called a voltmeter. It is linked simultaneously. It typically has a high resistance such that it uses very low circuit current. Voltmeters can be used to measure sinusoidal AC voltages as well as DC voltage, however …
What is a Capacitor? A Capacitor is a type of electronic device that consists of two electrically conducting plates that are spaced apart by an insulator. Based on the capacitor’s capacity to store and discharge current, it is utilised in electrical applications and circuits that use both direct current (DC) and alternating current (AC) to …

NDT test is a method to find the possibility of defects and the characteristics of a material that might cause aircraft to experience interference, reactor failure, train derailments, burst pipes, and various other events. NDT is used to ensure the quality of materials and joining procedures during the development and erection phases, and in-service NDT checks …
