Operating Principle

X-100 Roast Color Meter utilizes near infrared light to measure the roast degree of coffee beans. Near infrared light refers to the electromagnetic waves with wavelength of 750~1500 nm. According to the research, the absorption of near infrared light from coffee beans increases as the roast degree of coffee beans rises, while the reflection lowers down. This phenomenon comes from the carbonization of organic components inside the beans such as sucrose. Therefore, we can get the Agtron number and corresponding roast degree through measuring the reflection of infrared light from the beans and taking the SCA Agtron gourmet scale as reference.
