FlameSpec-IR3–H2 is the next generation of the IR3. It is being introduced to further enhance the protection and safety for those high risk and high value industries. The FlameSpec-IR3-H2 will detect hydrogen fires and explosions extremely fast, thus allowing preventative action to be initiated even more rapidly and minimizing the consequences! The unmatched detection times and distances are:

• Detection within 40 milliseconds of fireballs or explosions 
• 1.5s for 32″ (0.8m) hydrogen fire at 0–66 ft. (0–20m) 
• 4s for 32″ (0.8m) hydrogen fire at 66–100 ft. (20–30m) 

The FlameSpec-IR3-H2 flame detector provides ultra-fast response, high performance, and reliable detection of hydrogen fires. It operates in all weather and light conditions with the highest immunity to false alarms. These features, along with the built-in event logger, provide additional means to study the cause and development of fire events for “lessons learned” reviews​

FlameSpec-IR3–H2-HD has the addition of Integral HD quality video, with event recording, on top of the proven, superior capabilities of Triple IR (IR3) flame detection, providing a very powerful safety tool to protect personnel, plants, and processes. The detector's high-definition (HD) video output provides visualization of hydrogen flames that are invisible to the human eye. This allows the rescue team to be aware of the exact situation and location of invisible hydrogen flames before entering the hazardous area. The detector automatically records video of any fire event (1 minute pre- and up to 3 minutes post alarm initiation). These features, along with the built-in event logger, provide additional means to study the cause and development of fire events for “lessons learned” reviews 

FlameSpec-IR3-H2 and IR3-H2-HD:

• High immunity to false alarm, including arc welding.

• Detects, hydrogen, ammonia, methane & syngas flames using three infrared wavelengths, with clear separation.
