Advantages of SF6 Gas Test

Improved Safety and Reliability
Regular testing identifies early-stage internal faults, such as partial discharge or arcing, preventing catastrophic equipment explosions and failures.
Optimal Performance
By analyzing the gas, technicians can ensure that the SF6 maintains its superior dielectric strength, essential for effective arc quenching in circuit breakers.


Reduced Maintenance Costs
Testing provides a diagnostic "blood test" for equipment, allowing maintenance to be done based on actual condition rather than fixed schedules.
Extended Equipment Life
Regular monitoring helps detect and manage moisture and decomposition products if left unchecked, cause corrosive damage to internal components.

Self-calibration: The sensor probe can automatically calibrate the zero point, automatically eliminate the system error caused by the zero point and drift, and ensure the accuracy of each measurement.
Quick gas saving: After opening the machine into the measurement state, the dew point determination time is about 5 min.
Self locking joint: Imported self locking joint is safe and reliable without leakage.
Data storage: Large capacity design, which can store up to 1000 sets of test data.
Display clear: 5 inch ultra-large high-definition touch LCD screen directly display dew point, micro-water (ppm), environmental temperature, environmental humidity and other parameters and dates.
Application of SF6 Gas Test
SF6 gas test is a critical diagnostic procedure for high-voltage electrical equipment (GIS, circuit breakers) to ensure insulation integrity and arc-quenching performance. Key applications include measuring gas purity, moisture content, and decomposition products to prevent equipment failure, ensure safety, and monitor compliance with environmental regulations against leakage.
Gas Inlet/Outlet Ports: Self-sealing quick-couplings (e.g., DN8 or DN20) used to connect to electrical equipment for sampling and returning the gas, ensuring an emission-free process.
Internal Pump: A pump that draws the gas sample into the instrument. Some units are "pump-back" analyzers, meaning they return the tested gas back to the circuit breaker after analysis.
Flow Controller/Filter: A micro-flow control system that stabilizes gas flow, along with filters to remove particles and moisture from the sample.
Non-Dispersive Infrared (NDIR) Sensor: The primary sensor used for measuring.
Moisture Sensor (H₂O)
Commonly an aluminum oxide sensor or a chilled-mirror sensor for measuring dew point.
Color Touchscreen Display
A large LCD screen (often 7 inches or larger) for displaying data, operating the device, and displaying real-time curves.
Power and Structural Components
Provides power for field operation, allowing for over 8 hours of continuous use, and is typically rechargeable.
