Application areas
Petrochemicals, natural gas, industrial gases, the semiconductor industry, the drying industry, the food industry, the power industry, mechanical manufacturing, air separation industry, and the pharmaceutical industry.
Detection Principle
The dew-point meter employs a capacitive dew-point sensor and a crystal oscillator-based sensor imported from Mettler-Toledo/Vaisala, offering fast response and high sensitivity. It is easy to operate and can measure trace amounts of moisture in various gases, enabling continuous, automatic, and rapid online detection of moisture content in a wide range of gases.
