SF6 Leak Detector (Qualitative)

Qualitative SF6 Gas Leak Detection  |  0.01-500ppm for Circuit Breakers
Product Overview

This qualitative SF6 leak detector is designed for fast, reliable detection of sulfur hexafluoride gas leakage from circuit breakers and SF6-filled equipment. The working principle is based on the fact that when the concentration of SF6 gas in the air changes, the ionization degree of the mixed gas under the action of a high-frequency electromagnetic field varies accordingly; the SF6 concentration is reflected by detecting the ionization degree. With a separate probe and main unit, a small vacuum pump draws samples through a 4-meter pipe, while an LCD display shows the gas concentration and an audible alarm sounds automatically when the measured value reaches the set threshold.

Applications & Target Audience: Engineered for live-line working centers, customs and import-export inspection agencies, work safety supervision and occupational health organizations, hydrogen energy and fuel cell infrastructure projects and UAV and robotic inspection service providers that need to detect SF6 gas leakage from circuit breakers and gas-filled equipment for equipment integrity, personnel safety, emission compliance and inspection verification.

Performance Features
High-Frequency Ionization Principle: Concentration is determined by measuring the ionization degree of the air-gas mixture under a high-frequency electromagnetic field, providing stable and repeatable readings.
Split Probe with Vacuum Pump: The separate probe and main unit with a 0.5 liters/second vacuum pump and 4-meter pipe reach confined spaces and elevated breaker connections easily.
Non-Toxic Safe Probe: The probe is non-toxic and does not produce toxic gases, ensuring operator safety during prolonged leak surveys.
Automatic Audible Alarm: When the measured gas concentration is greater than or equal to the set value, the instrument automatically emits an alarm sound for hands-free operation.
Fast 3-Second Response: Rapid response time supports efficient scanning of circuit breaker bays and switchyards without missing transient leak signals.
Wide 0.01-500ppm Range: Covers both fine leak tracing and gross leak confirmation, with LCD digital display and visual alarm for clear indication.
SF6 Leak Risks and Compliance
Insulation Performance Degradation: SF6 leakage reduces gas pressure and dielectric strength inside circuit breakers and GIS chambers, increasing the risk of internal flashover and equipment failure.
Greenhouse Gas Emissions: SF6 has one of the highest global warming potentials of any industrial gas; systematic leak detection supports emission reduction targets and sustainability reporting.
Personnel and Environmental Safety: Decomposition products of SF6 under arcing can be harmful; early leak detection protects maintenance personnel and the surrounding environment.
Regulatory Compliance: Utilities and industrial users are increasingly required to document SF6 inventory and leakage under environmental and safety regulations.
Cost Control: Early detection of small leaks avoids expensive emergency gas refilling, unplanned outages and extended downtime of critical switchgear.

FAQ
Q1: What is this SF6 leak detector used for?
It is used for qualitative detection of sulfur hexafluoride gas leakage from circuit breakers, GIS chambers, flanges, valves and pipe connections, with a measurement range of 0.01ppm to 500ppm.
Q2: How does the detector measure SF6 concentration?
It measures the ionization degree of the air-gas mixture under a high-frequency electromagnetic field; changes in SF6 concentration cause corresponding changes in ionization, from which the concentration is determined.
Q3: How is the result indicated?
The concentration is shown on an LCD digital display, and the instrument automatically emits an audible alarm plus visual alarm signal when the measured concentration reaches the set value.
Q4: What is the advantage of the split type design?
The separate probe and main unit, with a small vacuum pump and 4-meter pipe, allow convenient access to confined spaces and hard-to-reach breaker connections while keeping the display and controls at hand.
Q5: What are the operating conditions?
The detector operates on AC 220V 50Hz at 7 to 40 degrees C with humidity up to 85%, and supports continuous operation for up to 4 hours.
