The IR3-H2 flame detector provides ulta-fast response, high performance and reliable detection for a number of fires found in Energy Transition applications, such as hydrogen, methane, syngas, ammonia and methanol.

The detector addresses slow growing fires as well as fast eruptions of fire using improved IR3 technology. The detector operates in all weather and light conditions.

These features, along with the built-in event logger, provide additional means to study the cause and development of fire events.
