Gastron Gas Detector G-Finder™ Universal B1 GFU-B1

Gastron Gas Detector G-Finder™ Universal B1

The GFU-B1 features a universal transmitter structure compatible with various sensors. It allows for immediate compatibility when swapping sensors from contact catalytic bead type to

electrochemical or infrared types. Additionally, it can be modified into Insert type or Remote type as needed. Through this technology, the GFU-B1 ensures consistent safety across all sites.

-Detects 1 to 3 channels of target gases, including flammable, toxic gases, and oxygen.

-The first explosion-proof gas detector in South Korea that can simultaneously mount more than two types of sensors.

-Features a universal transmitter structure that is immediately compatible with other types of sensors.

-Includes the first SIL2-based detecting sensitivity diagnostic system in South Korea.

-Equipped with Bluetooth functionality that connects with a smartphone app.

-Includes the first external HART port with intrinsic safety explosion-proof structure in South Korea.

-Enable rapid situation judgement through the Korean first diversified lightning system.
