Product Description
Portable SF6 Leak Detector For GIS Field Inspection & Switchgear Maintenance
Product Overview
The LF-200 high-sensitivity portable SF6 quantitative leak detector is a second-generation fully upgraded model iterated from the classic LF-1D and LF-1D+ series. Optimized for outstanding portability, operational simplicity and field reliability, it fully meets the high-standard testing demands for substation patrol inspection and GIS cabinet manufacturing.
Adopting the mature high-frequency magnetic field low-voltage ionization principle, the LF-200 is the optimal portable testing tool for detecting ultra-fine and slow SF6 micro-leakage, serving as the best high-sensitivity on-site leak detection solution for power and electrical industries.
Equipped with an exclusive patented auxiliary startup mechanism, the detector achieves a 100% successful startup rate. Featuring a split lightweight structure with an overall net weight of only 6.6 kg and a metal anti-collision aluminum alloy casing, it supports long-distance portable field carrying. With intelligent automatic vacuum detection and startup environment judgment, the device realizes fully automatic foolproof operation. It delivers fast, convenient, reliable and ultra-precise SF6 leak detection performance with zero wearing parts and extremely low operation and maintenance costs.

Why Portable SF6 Leak Detection Matters
During GIS maintenance and electrical field inspection, engineers need to rapidly locate micro and slow SF6 leakage points in complex outdoor environments. Conventional leak detectors are usually bulky, heavy and inconvenient for long-distance mobile inspection.
Field Inspection Requirements:
  • Stable and 100% successful startup performance
  • Fast response for micro and slow leakage detection
  • Ultra-lightweight portable structure
  • High stability for outdoor field operation
  • Durable and anti-collision design for frequent carrying
Lightweight portable SF6 leak detectors greatly improve on-site inspection efficiency and reduce manual workload, making them essential equipment for modern GIS operation, maintenance and substation inspection work.

LF-200 Portable SF6 Leak Detection Core Advantages

1. Patented 100% Successful Startup
Technology
The exclusive auxiliary startup device ensures
one-time successful ignition and startup every time,
effectively avoiding startup failure problems common
in conventional leak detectors.
2. Upgraded High-Vacuum Pump
System
The optimized high-vacuum pump greatly improves
the suction efficiency of leaked gas, accurately
restores the real gas concentration at leakage
points, and ensures no missed or false detection
of micro-leakages.
3. Fully Automatic Foolproof
Operation
The equipment automatically detects internal
vacuum degree and judges the ambient startup
environment. After the vacuum pump runs for
approximately 5 minutes, the detector automatically
activates and enters the working state, realizing
unattended intelligent operation.
4. Anti-Pollution & Anti-Poisoning ,
Protection Design
Unique continuous air suction and exhaust structure
effectively prevents sensor “poisoning”, dust and
oil pollution. The equipment can quickly recover to
normal working state after long-term operation, with
no vulnerable parts and ultra-low daily use cost.
5. Intelligent Fault Diagnosis &
Simplified After-Sales Maintenance
Equipped with dedicated fault indicator points, users
can quickly judge the equipment operating status
and standardize operation. Matched with simple
self-maintenance methods, it greatly reduces
after-sales service pressure and improves user
experience.

Applications of LF-200 Portable SF6 Leak Detector

Substation Patrol & Maintenance
Lightweight portable design supports daily patrol inspection, regular equipment maintenance and hidden danger
investigation of power grid equipment.
Professional Electrical Service
Widely used by electrical maintenance contractors and power inspection institutions for high-precision SF6 leak
detection services.

How the Portable SF6 Leak Detector Works
The LF-200 operates based on the high-frequency magnetic field low-voltage ionization principle. The built-in high-vacuum pump continuously samples ambient air and extracts trace SF6 gas. The high-sensitivity sensor quantitatively analyzes gas concentration and accurately identifies slow and tiny leakage points.

With automatic vacuum detection and environment judgment functions, the equipment completes preheating and self-inspection intelligently and enters the detection state automatically. The unique circulating suction and exhaust design ensures rapid equipment recovery, stable long-term operation and strong anti-interference ability against on-site dust and oil pollution.
