PROBLEM TO BE SOLVED: To provide a liquid volatility measuring device capable of heating a liquid sample without the use of a wood alloy for heat transfer between a heating block and a sample to be tested by a Noack test to measure the volatility, and a liquid volatility measuring method using the device. SOLUTION: A heating chamber includes a cylindrical evaporation boat 1 connected to a vacuum pump for receiving a tested sample, which is closed by a cover 2. The mechanical heating member and dry type contact heat transfer members 5, 6, 8 are electrically controlled and the evaporation boat 1 is surrounded by them. A temperature probe 4 pierces the cover 2 of the evaporation boat 1 to be immersed to a depth of a distance H from the bottom of the evaporation boat 1. A control member regulates the temperature of a sample in cooperation with a clock, the temperature probe 4 and heating and heat transfer members 5, 6, 8, and the member is automatically monitored by a microprocessor for performing connection or non-connection of the heating and heat transfer members 5, 6, 8 in cooperation with the clock.
