Intelligent Gas Monitors GT

The latest mechanical and electrical technologies offer a state-of-the-art design for any gas detection need. The GT Series Gas Monitors, developed by Focused Photonics (Hang Zhou) Inc. (FPI), provide continuous monitoring of hazardous gases.

Advanced sensing technologies monitor against the threat of combustible and toxic gases and for oxygen deficiency, utilizing catalytic and electrochemical gas detection methods.

GT Series Gas Monitors are suitable for indoor and outdoor applications in virtually any type of industry including refineries, chemical and petrochemical facilities, steel mills, water and wastewater plants, mining, and general industry.

GT Series Gas Monitors, can operate completely stand-alone with a large LCD display, remote controller, or connected with a standard 4-20mA output to a control system (PLC, DCS, etc.).
