The early detection of hydrogen leaks is critical to maintaining safety across the hydrogen lifecycle – from production to storage, transport, usage in fuel cells and H2 ICE.
With a wide accuracy range between 0 – 20% and ultra-low power consumption, H Guard maximises safety and operational reliability.

The configurable CAN bus speed and address along with the supplied CAN DBC file allows easy integration into almost any hydrogen system to detect hydrogen leaks or early battery pack failure due to cell venting or formation of moisture.

The unit features a low power mode in which it monitors the environment but does not transmit on CAN unless a threshold is reached; at which point it reverts to normal mode. It also features a low side drive function pin capable of 500mA that can be triggered if a programmable threshold is breached.

The 5-pin automotive rated Molex Nano-Fit Power connector, small size and mass allows easy interface into most systems.

For seamless connectivity, H Guard works perfectly with the Nano Development Kit for rapid desktop analysis.

The unit has been tested to automotive standards which include: ISO7637-2 2011, ISO 17650- 2 2012 and ISO 17650-4 2010.

ATEX rating is in progress.
