A portable combustible gas detector designed to detect methane, propane, and isobutane. The device features a 2.0" color TFT screen, three alarm modes (audible, visual, and vibrating), and a flexible 36 cm probe for easy access to hard-to-reach areas. A response time of less than 5 seconds and the ability to record up to 30 alarm events ensure fast and precise threat detection. Fnirsi GD-02
FNIRSI GD-02 is a portable, multifunctional combustible gas detector equipped with a 2.0” color TFT display, designed for detecting methane, propane, and isobutane. The device provides a fast response and high measurement accuracy, enabling real-time detection of even small gas concentrations. Thanks to the trend analysis function with a 0.5-second refresh rate, users can continuously and precisely monitor gas concentration changes. The detector also features a built-in temperature and humidity sensor for comprehensive environmental monitoring.

The GD-02 model stands out with its three alarm modes – sound, vibration, and light – which immediately alert the user to dangerous gas concentrations. The event memory function allows storage of up to 30 alarm records for later analysis, enhancing operational safety. Additionally, the device is equipped with a flexible 36 cm probe that facilitates gas detection in hard-to-reach areas, such as pipelines, fittings, and confined spaces. An integrated LED flashlight makes it easier to work in dark environments or outdoor locations.
The GD-02 detector features a response time of less than 5 seconds and a recovery time of under 10 seconds, making it an ideal tool for professional safety monitoring. Its sensor lifespan exceeds 3 years, and the interference-resistant design ensures stable operation even in demanding industrial environments. The device operates over a wide temperature range of -10°C to +55°C, maintaining accuracy and reliability.
The Data Hold function allows users to pause and analyze readings, while the built-in USB Type-C port enables firmware updates and device charging. The detector is lightweight, ergonomic, and easy to use thanks to its intuitive interface. FNIRSI® GD-02 is a reliable tool for monitoring gas leaks in homes, industrial facilities, workshops, and during maintenance operations, ensuring a high level of safety and control.
