The Alcor JFTOT 230 Mark IV (JFTOT IV) is a new jet-fuel thermal oxidation analyzer designed for increased safety and simplicity. New safety measures in this compact model ensure minimal jet-fuel vapor-exposure to personnel and the environment through the sample and waste containers. The sliding test door also prevents exposure to the high-temperature heater-tube test section. The JFTOT IV simplifies operational capabilities through automation of tasks, such as priming the pump, monitoring sample flow and aerating the sample. The JFTOT IV is listed in Table 1 of ASTM D3241-13, “Standard Test Method for Thermal Oxidation Stability of Aviation Turbine Fuels,” as an acceptable instrument model. — The Petroleum Analyzer Company (PAC), L.P., Houston, Tex.
