FNIRSI GD-02 Combustible 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 comfort of use both during the day and at night. It is a tool designed for safety, convenience, and full control.

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 installations in motorhomes. One compact meter replaces several tools and ensures that no leak will escape your attention.

An impressive range of up to 50,000 ppm – precision without compromise

The measuring range of 0–50,000 ppm (CH₄) and 0–100% 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 the right action.

Express response when every second counts

A sampling time of ~0.5 s, a T90 response of < 5 s, and a fast T10 recovery 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.

Color IPS 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.

Smart curve visualization – see more

Smart Curve Data Visualization mode allows you to observe 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 is changing – a huge advantage in diagnosing installations and locating leaks.

Flexible 36 cm probe – you can reach places others cannot

The rotating, flexible 36 cm probe allows you to inspect hard-to-reach places: crevices, corners, spaces behind appliances, or along pipes. Full 360° flexibility means comfortable work and precise leak source detection.

Triple alarm system – safety you can hear and see

The 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 sets of alarm data for later analysis.

Ready for the dark – flashlight and night mode

The built-in LED flashlight, backlight, and switching between day and night modes make the detector ideal for basements, boiler rooms, garages, or night inspections. Visibility and comfort are maintained in every situation.

Long operation and intelligent energy saving

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

Firmware updates – equipment that evolves

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 construction for years of service

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