UHV-620 SF6 Micro Water Tester is a portable instrument designed to accurately measure dew point and trace moisture content in SF6, air, N2 and other non-corrosive gases. It is intended for on-site testing, gas acceptance and filling monitoring, and maintenance in power systems and industrial environments.

Key features:

• High precision and sensitivity, capable of detecting trace moisture at ppm and ppb levels.
• Fast response times for efficient on-site measurements.
• Designed for portability and field use.
• Data traceability with storage and export functions for quality control and fault analysis.
• User-friendly interface to minimize operator training.
• Reliable monitoring to help prevent insulation degradation and equipment failures.

Main application scenarios:

• Power systems: acceptance tests, preventive checks and fault diagnosis of SF6 equipment (GIS, circuit breakers, transformers, bushings).
• Monitoring SF6 during filling, recovery and to prevent insulation degradation, corrosion and freezing at low temperatures.
• Semiconductor manufacturing: moisture control for high-purity process gases (N2, Ar, H2).
• Chemical industry: control of moisture in reaction, protective and carrier gases.
• Compressed air systems: dew point detection to prevent pipeline corrosion and instrument malfunction.
• Lithium battery production: dew point monitoring in drying rooms and glove boxes with inert gases.
• Pharmaceuticals and research: precise gas humidity control for processes and experiments.
