Dew Point Meters


Dew Point Meters are special devices designed to measure temperature to deterring the dew point, it is the name given to a certain temperature. A constant biometric pressure of air must be cooled for water vapour to condense, the condensed water vapour turns into water; this whole process takes place when the dew point is met. It is a saturation point, but when the point falls below freezing it changes to what is known as the frost point, this is because the water vapour stops turning into water but changes in to hoarfrost or frost by deposition.

The meters are used to determine when this 'certain point' is met; it uses sensors to detect changes in temperature and humidity. Relative humidity is associated with the dew point and the closer to the current air temperature it is a high relative humidity would be indicated.

The measurement of this point is most commonly required during in field application of paint systems and in fact the meter used to measure it becomes the most critical analysis device. Another name given to this meter is the Dewpoint Gauge and was invented by TQC, this model was designed specifically for the coating industry and is the most used measuring device in that industry. This device also falls under another name that is more likely to be used in shops, if you are looking for this device but can not find it try asking for a 'Dewcheck'. There are a lot of suppliers available you just need to look around.




If you are in need of this service check out our product pages, they contain many companies that specialise in this. Wesley Clarke writes about Dew Point Meters. Visit the Businessmagnet product page for details and suppliers of Dew Point Meters.
