Analytical Instrumentation

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.

Conductivity Meter

Conductivity Measurement Principle

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 …

Importance of an Intrinsically safe system 1

What is intrinsically safe system and what is its importance?

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 …

What is Ammeter?

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 …
