High Light CH₄ Gas Leak Detector ，Multi-Component Gas Leak Detector ，CO₂ Gas Leak Detector
Multi-Component Gas Leak Detector LF-01-FR (Suitable for SF₆/SO₂/CH₄/CO₂ & More Gases)
The LF-01-FR Multi-Component Gas Leak Detector is a versatile gas detection device integrating Dual Detection Technologies: Infrared (NDIR) and Electrochemistry. Its core advantage lies in the ability to accurately capture leak signals of multiple gases simultaneously, adapting to complex industrial environments such as high/low temperature, high humidity, and high dust. Combining fast response, user-friendly operation, and intelligent data management, it provides an efficient solution for gas safety monitoring in industries like petroleum, electric power, and chemical engineering.
I. Core Product Advantages
1. Infrared Precision Detection with Strong Anti-Interference Capability
Equipped with an NDIR (Non-Dispersive Infrared) sensor, it enables high-precision measurement for infrared-sensitive gases (e.g., SF₆, CO₂, CH₄):
  • Automatically filters environmental impurities such as oil, water, and dust, preventing interference signals from affecting detection results;
  • Features fast response speed, allowing quick localization of leak points and reducing the risks of missed detection and false detection.
2. Humanized Design for Easier Operation and Portability
  • Clear Visual Interface: Equipped with a 3.5-inch HD color display (resolution: 480×320), which intuitively presents real-time data, concentration curves, alarm status, and other information without complicated interpretation;
  • Low-Power & Efficient Control: Pure hardware one-key on/off design reduces unnecessary power consumption and extends battery life;
  • Flexible Adaptation to Complex Scenarios: Optional long-handle suction probe tube for easy access to hard-to-reach areas such as equipment gaps and high-altitude pipelines;
  • Portable Mobility: Comes with a standard leather shoulder bag; the whole machine weighs only about 500g, facilitating on-site personnel to operate it by hand or carry it on the shoulder.
3. Comprehensive Functions to Meet Diverse Detection Needs
  • Multi-Dimensional Data Presentation: Simultaneously displays real-time detection values and concentration change curves, enabling intuitive grasp of gas leak trends;
  • Flexible Sampling Adjustment: Built-in adjustable speed air pump (0-500cc/Min) for flexible switching between high and low sampling speeds according to leak scenarios;
  • Simultaneous Multi-Gas Detection: Supports simultaneous detection of up to 4 infrared-sensitive gases (configurable on demand), eliminating the need for frequent equipment replacement;
  • Intelligent Data Management:
    • Supports Chinese/English interface switching and automatic gas unit conversion (calculated by the intelligent system);
    • Standard 8G SD card for data storage (16G/32G optional); recording interval is customizable for long-term storage of massive data;
    • Enables fast data export (in TXT format) via Micro-USB and Android data cables; optional external Bluetooth printer for on-site instant printing of detection reports;
  • Strong Environmental Adaptability: Combined with a sampling probe gun, it can work stably in high-temperature (-20℃~50℃, up to 1200℃ with flue gas probe gun), high-humidity (0-95%RH, non-condensing; optional filter for high humidity), and high-dust environments.
