FGARD H2
The Fgard H2 is a breakthrough in hydrogen flame detection, delivering first-in-class flame detection with intelligent heated optics for clearer results, and advanced optical verification to greatly reduce false alarms.
Where to BuyIn industries reliant on hydrogen, detecting its colourless gas and flame presents a critical safety concern. Unlike traditional multi-spectral flame detectors, which lack the capability to discern hydrogen flames, the Fgard H2 is optimised exclusively for hydrogen flame detection, ensuring your people and your facilities are kept safe.
The Fgard H2 delivers unparalleled performance, with a response time of just 4 seconds ensuring swift and reliable detection even in demanding industrial environments.
Its intelligent heated optics mean there is no condensation, ice, or water build up on the sensor, with advanced optical verification and automatic tests verify the cleanliness of the lens and electronic circuitry.
Designed to minimise the risk of false alarms, the Fgard H2 is setting a new standard in reliability, with a market-leading 5 year warranty period for a hydrogen flame detector. This commitment to quality is underscored by the endorsement of Factory Mutual (FM), validating the performance of Fgard H2 for complete peace of mind.
