Techniques were investigated for rapid, non-destructive measurement of the temp. of individual grain kernels. Single kernel temp. is of interest for materials property research, including moisture measurement where a correlation exists with temp. rise during microwave heating. Slightly modified, commercial miniature thermocouples, infrared, and fluoroptic temp. measurement devices were tested on grains (maize, peanut, and sunflower) representing a range in size, shape, surface irregularity, internal non-homogeneity, and m.c. Miniature thermocouple and fluoroptic probes were found unsuitable for single kernel temp. measurement because of their relatively large mass, slow response time, and the difficulty of achieving adequate surface contact. The infrared sensor had good accuracy, negligible effect on the sample, and short response time
