FNIRSI GD-02 Flammable Gas Detector

The FNIRSI GD-02 portable flammable gas detector with a colour screen.
The FNIRSI GD-02 is a compact, portable flammable gas detector fitted with a 2.0" colour TFT display, designed for the rapid and accurate identification of gas leaks such as methane, propane and isobutane. The device is designed for both domestic and professional use, for example during inspections. Thanks to its highly sensitive semiconductor sensor, it can detect even the smallest leaks at the earliest stage. As soon as the gas concentration exceeds the safe limit, the device immediately alerts you with an audible, visual and vibrating alarm. Compact, lightweight construction and an ergonomic, hand-held design that fits easily into a pocket or toolbox.


Ideal uses: - domestic checks: inspecting gas cookers, boilers, space heaters and connecting hoses - car/motorbike inspections: detecting leaks in LPG/CNG systems in cars or caravans
- holiday home owners and camping: safety checks on propane-butane cylinders and cookers - professional use: an essential tool for plumbers, gas engineers, inspection technicians and maintenance staff. Product specifications:

- Gases detected: methane, propane, isobutane and other flammable mixtures (LPG) - Measurement range: 0–50,000 ppm (or 0–100% LEL) with a resolution of 1 ppm
- 36 cm flexible probe: easy detection in complex, narrow or hard-to-reach spaces - triple alarm: if a leak is detected, the device alerts you with an audible alarm (buzzer), vibrations and a visual indication on the display
- Flexible probe: the 36 cm long ‘gooseneck’ allows access to narrow and hard-to-reach areas
- colour display: shows gas concentration in real time, including a trend graph, ambient temperature and humidity
- Curve analysis and data logging: supports trend curve analysis and data logging for more intuitive monitoring - Power supply: built-in 1500mAh lithium battery, rechargeable via a modern USB-C port
- Long sensor life: durable sensor with over 3 years of reliable operation - Lightweight and portable design: weighs approximately 296 g, with a built-in torch for use in low light or emergency situations
