Abstract
A testing device and method for determining smoke point of a hydrocarbon. The device including: an apparatus for determining the smoke point conforming to specifications of an ASTM D1322-19 standard or equivalent standard, imaging device for taking a series of digital images of a flame; ambient relative humidity sensor for measuring relative humidity; ambient temperature sensor for measuring temperature; computer system linked to the imaging device, humidity sensor, and temperature sensor programmed to analyze digital images from the imaging device to measure flame height flame, and use temperature with relative humidity measured by the temperature and humidity sensors to calculate absolute humidity and correct measured flame height as a function of difference between the calculated absolute humidity and normalized absolute humidity, and preferably to correct measured flame height as a function of difference between pressure during flame height measuring and normalized pressure.
