In critical industrial operations, monitoring and controlling trace moisture content in industrial gases is essential to safeguard equipment integrity, maintain process reliability, and prevent costly operational failures. The Portable Dew Point Tester is a high-precision intelligent instrument engineered to accurately measure dew point values and trace moisture content in SF6 gas as well as various non-corrosive gases.

Built with an original imported high-precision dew point sensor and the latest digital circuit control technology, this analyzer delivers reliable measurement performance characterized by fast response speed, high accuracy, good linearity, and a real-time dynamic display of the measurement curve.

Core Functions of the Instrument The Portable Dew Point Tester is designed to test dew point values and measure water content across a wide range of non-corrosive gas media, including:

• Measuring trace moisture and water content in SF6 gas to accurately identify its arc extinguishing performance in high-voltage power equipment.
• Testing dew point values in compressed or ambient industrial air.
• Analyzing trace moisture levels in nitrogen gas.
• Measuring dew point values in inert gases and any other gas applications free from corrosive gases.

Industrial Applications Offering exceptional cost performance, this portable dew point analyzer is widely utilized across key industrial and research sectors, including:

• Electric Power Industry: Inspecting the moisture content of SF6 insulation gas in switchgear, circuit breakers, and power substations to ensure reliable arc extinguishing performance.
• Petrochemical Industry: Monitoring gas dryness in process pipelines, instrument air systems, and nitrogen purging networks.
• Metallurgy Industry: Controlling moisture levels in protective and inert gases used during heat treatment and metal processing.
• Environmental Protection: Supporting gas quality monitoring and compliance verification across industrial facilities.
