The caramelization tester (Agtron), or "Aiko instrument", is an optical instrument that uses infrared wavelength to determine the roasting degree of coffee. This instrument can determine the degree of caramelization of sugar in coffee beans and present it in a way. This table shows that the range from shallow roasting to heavy roasting is 25: 100, but according to the technical standardization committee of SCAA, the recognizable range of coffee flavor is actually 30: 90.
