LF-01-FR is a handheld multi-gas analyzer with infrared and electrochemical sensing technology for SF6 and industrial gas detection.
LF-01-FR is a handheld multi-gas infrared detector designed for industrial gas monitoring and environmental safety applications. The device integrates infrared (NDIR), electrochemical, catalytic combustion and PID sensing technologies, allowing simultaneous detection of up to four gases.
Equipped with a built-in filtration system, LF-01-FR effectively removes oil, moisture and dust impurities, ensuring stable and accurate measurement even in harsh industrial environments.
The detector features a 3.5-inch HD color display, adjustable pump flow, real-time concentration curve display, large-capacity data storage and optional Bluetooth printing, making it ideal for field inspection and industrial maintenance.
Built-in filtration system efficiently filters oil, water and dust impurities for stable and accurate gas analysis.
Compact handheld structure with leather carrying bag for easy field operation.
Supports simultaneous detection of up to 4 gases with customizable sensor combinations.
Simultaneously displays:
Built-in gas pump with adjustable flow rate: 0-500 mL/min
Supports external Bluetooth printer for on-site concentration data and curve printing.
Suitable for harsh environments including high temperature, high humidity, and dusty environments. Optional sampling probe available for flue gas up to 1200°C.
