What is a dew point meter? What is a dew point? We will introduce the types of dew point meters and their measurement principles.
■What is a Dew Point Meter? A device that measures trace amounts of moisture contained in gases such as gas or dry air. It is expressed in terms of the temperature at which moisture in the gas condenses, known as the dew point temperature (°C dp). ■What is Dew Point? The temperature at which condensation, or the process of liquefaction, occurs when cooling a gas. This ultimately represents the temperature at which air is in equilibrium with water and is saturated. The dew point is an important factor not only in everyday life but also in various industrial fields (such as painting, semiconductors, batteries, power, railways, pharmaceuticals, gas refining, renewable energy, chemical plants, agriculture, food, air, industrial gases, steel, air conditioning, heat treatment, etc.). ■Types of Dew Point Meters There are several types of dew point meters based on measurement principles. The dew point meters currently in use are as follows: 1) Capacitive Dew Point Meter (Aluminum Oxide) 2) Capacitive Dew Point Meter (Polymer) 3) Mirror-Cooling Dew Point Meter 4) Phosphorus Pentoxide Dew Point Meter 5) Laser Dew Point Meter
