The High-precision SF6 Gas Leakage Detector is designed for reliable localization of SF6 gas leakage points in high-voltage equipment maintenance. It identifies leakage by continuously monitoring SF6 concentration levels, triggering configurable audible and visual alarms once preset thresholds are reached, and presenting real-time trend curves for diagnostic evaluation. This allows maintenance teams to quickly trace leakage sources and improve the operational safety of GIS and SF6-insulated systems.
From a SF6 Gas Leakage Detector manufacturer and supplier in China, UHV focuses on industrial-grade sensor stability, fast response performance, and long-term field reliability. The system is engineered to support both routine inspection and critical outage maintenance, ensuring accurate detection even in low-concentration leakage environments commonly encountered in substations and switchgear rooms.
As a professional solution widely adopted by power utilities, the SF6 Gas Leakage Detector supplied by leading China-based manufacturers and suppliers integrates high-sensitivity detection modules with intelligent alarm logic and data trend analysis. This provides not only point leakage identification but also predictive maintenance support for SF6 gas insulation systems.

Scope of use
The SF6 Gas Leakage Detector is suitable for leak detection of equipment and containers filled with sulfur hexafluoride gas in departments such as power, railway, electrical manufacturing, chemical, fire-fighting equipment, and atomic physics research. It can quickly and accurately perform qualitative and quantitative measurement and analysis of sulfur hexafluoride gas. It is also suitable as a supporting instrument for SF6 electrical equipment and export products in SF6 high-voltage switchgear plants.
precautions
1. The operator needs to be familiar with the operating instructions and strictly follow the operating steps to carry out relevant operations.
2. Please do not place the instrument randomly to prevent dust, water, oil and other pollutants from entering the interior of the instrument, so as not to affect its performance.
3. When measuring outdoors in windy areas, it is advisable to cover up as much as possible to facilitate accurate measurements.
4. Before each measurement, the probe should be kept clean. If necessary, the probe can be removed for cleaning using a mild cleaning agent
Cleaning, drying treatment is required after cleaning.
FAQ
1. What is the difference between this detector and a qualitative leak detector?
The SF6 Gas Leakage Detector supplier is a quantitative leak detector. It measures the actual concentration of SF6 gas in ppm (parts per million), allowing you to determine not only where a leak is but also how severe it is. Qualitative detectors only indicate the presence of a leak, often with relative signal strength, without providing a concentration value.
2. How does the instrument help locate leaks?
It provides real-time detection data and dynamic waveform curve analysis charts. As the probe moves closer to a leak, the concentration reading increases and the curve changes accordingly. The audible alarm also increases in intensity, allowing the operator to pinpoint the exact location of the leak.
3. What are the key features for data management?
The SF6 Gas Leakage Detector manufactures can store up to 20,000 pieces of data and waveforms. It includes browsing and query functions for reviewing stored data. A clock perpetual calendar function provides time stamps for all records, which is useful for documentation and trend analysis.
4. How long does the battery last and how is it powered?
It is powered by a large-capacity rechargeable lithium battery that provides a continuous working time of more than 5 hours. The charging adapter specification is DC5V/1A.
