SWAS Analyzers Questions and Answers
Steam and water analysis system (SWAS) is a system dedicated to the analysis of steam or water. In power stations, it is usually used to analyze boiler steam and water...
Falling Ball Viscometer Principle
Falling Ball Viscometer uses the simple — but precise — Höppler principle to measure the viscosity of Newtonian liquids by measuring the time required for a ball to fall under...
Ionization chamber Principle
The ionization chamber is the simplest of all gas-filled radiation detectors, and is widely used for the detection and measurement of certain types of ionizing radiation; X-rays, gamma rays and beta particles. Conventionally, the term “ionization chamber”...
Scintillation Counter Principle
A scintillation counter is an instrument for detecting and measuring ionizing radiation by using the excitation effect of incident radiation on a scintillator material and detecting the resultant light pulses. It consists of...
Sling Psychrometer Principle
Sling Psychrometer is used to measure both the dry bulb and wet bulb temperatures at time. These temperatures are a measure of humidity content in air. Description of Sling Psychrometer...
Humidity Sensing Absorption Hydrometer Principle
A change in resistance with change in humidity is taken as a measure of humidity. This is type of Electrical Humidity sensing Absorption Hydrometer, know more about mechanical humidity sensing...
Hair Hydrometer Principle
Due to humidity, several materials experience a change in physical, chemical and electrical properties. This property is used in transducer that are designed and calibrated to read relative humidity directly. Hair...
Dew Point Meter Principle
Dew Point Meter Principle By Cooling at constant pressure if the temperature of air is reduced, the water-vapour in the air will start to condense at a particular temperature. This...
Analytical Standards
An analyzer measures intrinsic properties of a substance sample such as its density, chemical content, or purity. Whereas the other types of instruments discussed in this chapter measure quantities incidental...
