New Product Launch | Portable SF₆ Gas Leak Detector

Lanso Konly (Shanghai) Instruments Co., Ltd. proudly introduces the LSLF1001 Portable SF6 Gas Leak Detector, a high-precision quantitative detection instrument based on Non-Dispersive Infrared (NDIR) technology. Specifically designed for SF₆ gas leak detection, the instrument combines portability, accuracy, and practicality, making it an essential tool for equipment safety inspection, preventive maintenance, and routine operation across industries such as power generation and transmission, rail transportation, metallurgy, and petrochemicals.

I. Product Overview

The system consists of a main detector unit and a lightweight handheld sampling probe, and is supplied with a power adapter, sampling probe, USB flash drive, carrying strap, dedicated transport case, and user manual for immediate deployment.

Equipped with a high-capacity rechargeable lithium battery, the LSLF1001 Portable SF6 Gas Leak Detector supports extended field operation. Its intelligent software platform integrates multiple advanced functions, including multi-stage filtration, temperature and pressure compensation, and audible and visual alarm notifications. The instrument enables:

• Quantitative SF₆ concentration measurement
• Leak rate analysis
• Precise leak source localization
• Real-time self-monitoring of instrument operating status

Designed to meet the demands of complex industrial environments, the detector supports both portable handheld operation and bench-top stationary operation, providing maximum flexibility for various inspection scenarios.

II. Key Features

1. High-Precision Detection and Calibration

The instrument supports zero-point calibration, span calibration, and user-defined calibration, ensuring accurate quantitative measurement of SF₆ concentration and reliable leak rate analysis with excellent measurement stability.

2. Advanced Visualization

Featuring dual high-resolution color displays, each screen operates independently and can switch freely between real-time numerical readings and trend curve displays, enabling rapid identification of leak locations.

3. Intelligent Alarm System

A multi-level audible and visual alarm system allows users to define alarm thresholds. When gas concentration exceeds preset limits, alarms are triggered simultaneously through sound, indicator lights, and on-screen notifications for immediate response.

4. Comprehensive Data Management

Measurement data can be stored automatically or manually. Data export and firmware upgrades are supported via USB connectivity. The instrument also provides a bilingual Chinese-English user interface to accommodate diverse operating environments.

5. Smart Self-Diagnostics and Maintenance

The detector continuously monitors its operating condition through an intelligent self-diagnostic system and proactively issues maintenance reminders, helping reduce downtime and improve operational reliability.

6. Multiple Measurement Units

The system supports five selectable display units:

• ppmv
• g/s
• mL/s
• mbar·L/s
• g/y

This flexibility ensures compliance with measurement standards across different industries and applications.

III. Product Advantages

1. Outstanding Detection Performance

With a detection limit below 0.3 ppmv, the instrument delivers high sensitivity and rapid response while effectively minimizing cross-interference from other gases, enabling accurate detection of even trace-level leaks.

2. Excellent Environmental Adaptability

Designed for operation in temperatures ranging from −20°C to +50°C, the detector incorporates built-in temperature and pressure monitoring modules. Automatic compensation functions ensure reliable performance in challenging environments, including high-altitude locations.

3. Reliable Protection Design

The sampling system incorporates multi-stage filtration technology to effectively block dust, particles, and contaminants, protecting critical components and extending service life.

4. Long Battery Life and Portability

A high-capacity lithium battery provides more than 12 hours of continuous operation. The compact, lightweight design, combined with a dedicated carrying strap and transport case, makes the instrument ideal for field inspections and mobile leak detection tasks.

5. Stable Operation with Minimal Drift

The detector offers excellent long-term stability, with:

• Span drift ≤ ±10% FS
• Annual span drift ≤ ±1% FS/year

Outstanding repeatability ensures reliable measurement performance and data consistency throughout the instrument’s service life.

IV. Key Technical Specifications

V. Applications

The LSLF1001 Portable SF6 Gas Leak Detector is widely used for leak detection and routine inspection of high-voltage electrical equipment, Gas-Insulated Switchgear (GIS), and SF₆-insulated switching equipment within the power industry. It is also well suited for applications in the railway, metallurgy, and petrochemical sectors.

The instrument can be utilized for safety leak testing, preventive maintenance, and fault diagnostics of various SF₆-filled industrial vessels, sealed systems, and pipeline networks, helping organizations enhance operational safety, reduce environmental risks, and ensure reliable asset performance.
