Sparking Technology
• Sample and air flow past a heater and liquid space RTD sensor into the flash chamber
• Liquid overflows to drain, fuel-air vapors rise within chamber
• Heater gradually raises fuel-air temperature while electrode circuit generates a spark at user-defined intervals
• When the fuel-air mixture ignites, the vapor-space temperature spikes.
• The sample temperature at that point is reported as the flash point temperature
