Flame monitoring in a flash point determination or combustion point determination

A device for a flash point determination and/or combustion point determination of a liquid sample which is receivable in a container and for a flame detection, comprising:

• a container reception for receiving the container;
• an infrared sensor which is arranged to detect light which is generated by a flame in a region around or within the container;
• an evaluation system which is coupled with the infrared sensor and which is configured to evaluate infrared sensor data of the infrared sensor to indicate a fire and/or a burn of the liquid sample based on the evaluation;
• and
• a flame ionization detector with two electrodes, a voltage source to apply an electric voltage to an electrode of the two electrodes, and an adjustable resistance measurement circuit, to measure resistance data which indicate a resistance between the electrodes depending on an ionization of the flame for evaluating the sensor data by the evaluation system.
