FNIRSI® GD-02 Portable Combustible Gas Detector Color Screen Methane Propane Isobutane Monitor
The FNIRSI GD-02 is a portable combustible gas detector designed for fast and accurate gas leak detection in residential, commercial, and industrial applications. It supports the detection of methane, propane, and isobutane gases, making it suitable for gas pipeline inspection, kitchen safety monitoring, RV maintenance, HVAC servicing, and industrial safety checks. The device features a 2.0-inch full-color TFT display that shows real-time gas concentration along with environmental temperature and humidity information.
The detector includes a 36cm flexible probe for reaching confined or hard-to-access areas and uses a triple alarm system with sound, vibration, and visual alerts for improved safety. It also supports trend curve analysis, alarm record storage, adjustable brightness, and Type-C firmware updates. The compact rechargeable design and fast response time make the GD-02 suitable for field technicians, maintenance engineers, safety inspectors, and DIY users who require portable combustible gas monitoring.
