FNIRSI GD-02 is a practical combustible gas detector for quick leak checks at home and in professional service. It offers a wide measuring range up to 50,000 ppm, a clear 2" color IPS display, a flexible 36 cm probe for hard-to-reach areas, and a triple alarm (visual, audible, vibration) for maximum safety.

The FNIRSI GD-02 detector is designed for reliable detection of combustible gases such as methane (CH₄), propane (C₃H₈), isobutane, LPG, and natural gas. It is useful for checking gas installations, around stoves, water heaters, boilers, fireplaces, LPG cylinders, and in RVs/campervans. Thanks to its fast response, it provides information almost immediately and helps identify risks in time.

The large 2.0" IPS display shows readings in PPM and % LEL and also provides temperature information. A key advantage is the real-time concentration trend graph, which makes it easier to locate a leak and monitor how the situation develops. For work in low-light conditions, there is a LED flashlight and switching between day and night modes.

The flexible 36 cm probe with 360° rotation enables measurements in gaps, corners, and behind appliances. Safety is enhanced by the triple alarm and the option to store up to 30 alarm data records. The built-in 1500 mAh Li-ion battery, together with auto power-off, helps maintain long operating time. The device also supports firmware updates when connected to a computer.

Main advantages:

  • Multi-gas detection: methane, propane, isobutane, LPG, and natural gas
  • Range 0–50,000 ppm and 0–100 % LEL for normal and critical situations
  • Fast measurement: sampling ~0.5 s, T90 < 5 s
  • 2" color IPS display + real-time concentration graph
  • 36 cm flexible probe with 360° rotation
  • Visual, audible, and vibration alarm + logging up to 30 events
  • LED flashlight and day/night mode
  • 1500 mAh battery and auto power-off
