FNIRSI GD-02 flammable gas detector with color screen

FNIRSI GD-02 Combustible Gas Detector with Color Screen

The FNIRSI GD-02 is a modern combustible gas detector that combines high measurement precision, a wide detection range up to 50,000 ppm, a clear 2-inch IPS color screen, a flexible 36 cm probe, and advanced alarm systems. From the very first seconds of operation, it provides fast, reliable results, alarm data recording, real-time visualization of concentration changes, and ease of use both day and night. This tool was created with safety, convenience, and complete control in mind.

Wide detection – one device, many applications

The FNIRSI GD-02 detector detects methane, propane, and isobutane, making it ideal for gas installations, stoves, water heaters, furnaces, gas fireplaces, LPG cylinders, and RV installations. One compact meter replaces several tools and ensures that no leak will escape your attention.

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

The 0–50,000 ppm (CH₄) and 0–100% LEL measurement ranges allow you to detect both minimal leaks and actual explosion hazards. The high resolution of 1 ppm / 1% LEL ensures the device responds quickly, giving you time to take appropriate action.

Express response when every second counts

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

IPS color screen – readability in all conditions

The large 2-inch IPS screen provides 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.

Intelligent curve visualization – see more

Smart Curve Data Visualization mode allows you to observe gas concentration changes in real time on a graph. This not only lets you know that gas is present, but also how its level is changing – a huge advantage when diagnosing installations and locating leaks.

Flexible 36 cm probe – reach where others can't

The 36 cm rotating, flexible probe allows you to examine hard-to-reach places: crevices, corners, behind devices, and along pipes. Full 360° flexibility means comfortable operation and precise leak detection.

Triple alarm system – security you can hear and see

The FNIRSI GD-02 offers three types of alarms: visual, audible, and vibration. Regardless of the conditions—noise, darkness, or working with gloves—you'll always receive a clear warning of a threat. Additionally, the device saves up to 30 sets of alarm data for later analysis.

Ready for the Dark – Flashlight and Night Mode

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

Long-lasting and intelligent energy saving

The built-in 1500 mAh battery ensures long operating time, and the auto-off function protects the battery from unnecessary discharge. This means reliability you can count on for both short checks and long inspections.

Firmware Updates – Hardware That Evolves

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

Solid construction for years

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