FNIRSI GD-02 is a modern combustible gas detector with high measurement accuracy, a wide detection range up to 50,000 ppm, a clear 2-inch IPS color display, a flexible 36 cm probe and advanced alarm systems. From the first seconds of operation, it provides fast and reliable results, alarm data recording, real-time visualization of concentration changes and convenient use both day and night. It is a tool designed for safety, convenience and complete control.

Wide detection - one device, many applications

The FNIRSI GD-02 detector detects methane, propane and isobutane, making it ideal for gas appliances, stoves, water heaters, ovens, gas fireplaces, LPG cylinders and camper vans. One compact meter replaces several tools and ensures that no leak goes unnoticed.

Impressive range up to 50,000 ppm – accuracy without compromise

The measuring range from 0 to 50,000 ppm (CH₄) and 0 to 100% LEL allows you to detect both minimal leaks and real explosion hazards. The high resolution of 1 ppm / 1% LEL means that the device reacts instantly, giving you time to take appropriate action.

Fast response when every second counts

~0.5 s sampling time, < 5 s T90 response and fast < 10 s T10 recovery guarantee immediate information about changes in gas concentrations. The FNIRSI GD-02 is a detector that doesn’t keep you waiting – it works when you really need it.

Color IPS display – readability in any conditions

The large 2-inch IPS display ensures excellent data visibility from any angle. PPM and %LEL units, temperature in °C or °F, humidity, operating status – everything is presented clearly, aesthetically and intuitively, without guesswork or unnecessary complications.

Smart Curve Visualization – see more

The Smart Curve data visualization mode allows you to monitor changes in gas concentration in real time on a graph. This not only lets you know that gas is present, but also how its level changes – a huge advantage when diagnosing devices and detecting leaks.

Flexible 36 cm probe – you can reach places that others cannot reach

The rotating, flexible 36 cm probe allows you to inspect hard-to-reach places: cracks, corners, gaps behind devices or along pipes. Full 360° flexibility means comfortable work and accurate detection of the source of the leak.

Triple alarm system – safety you can hear and see

FNIRSI GD-02 offers 3 types of alarms: visual, audible and vibrating. Regardless of the conditions – noise, darkness or working with gloves – you will always receive a clear warning of danger. In addition, the device stores up to 30 alarm data sets for later analysis.

Ready for the dark – flashlight and night mode

The integrated LED flashlight, backlight and day/night mode switch make the detector ideal for basements, boiler rooms, garages or night inspections. Visibility and comfort are maintained in every situation.

Long operation and smart energy saving

The integrated 1500 mAh battery ensures a long operating time, and the automatic shutdown function protects the battery from unnecessary discharge. This is reliability you can rely on, whether you are carrying out short inspections or long inspections.

Software updates – equipment that improves

The ability to quickly update the software via a computer means that your detector can always perform even better. No need to send the device to a service center, no downtime - simple, convenient and modern.

Robust design for long service life

Compact dimensions, ergonomic shape, weight of approximately 296 g, durable housing and more than 3 years of sensor life make the FNIRSI GD-02 an investment in long-term security. A professional detector that will meet the expectations of installers, maintenance technicians and demanding home users.
