Lighttells CM-200 Coffee Roast Degree Uniformity Ground-Size Analyzer
The CM-200 Portable Coffee Roast Degree Uniformity Ground-Size Analyzer is designed to measure the roast degree, roast uniformity for both whole bean and ground bean, and it can also analyze the distribution of ground size. It is a useful portable tool with its user-friendly interface, accurate performance, and reliable quality.
It provides you accurate SCAA Gourmet numeric scales result and display a variety of name terminology corresponding to the result (Light, City, Italian, etc). Besides roast degree, it also provides the color uniformity of how your coffee beans were roasted, and if you would like to check how your grinder performs, the CM-200 can analyze the distribution of ground size, this would make your grinder calibration much easier.

HOW DOES IT WORK?
Like other coffee roast analyzers on the market, the CM-100 Plus uses an infrared photometer that reveals the caramelization of the coffee beans or coffee grounds. The analyzer shoots a laser beam down onto the surface of the beans (either whole or ground), and measures how much light reflects off the surface of the coffee and back into the analyzer. If the roast is darker, the bean will absorb more light and reflect less light back into the analyzer. If the roast is lighter, less light will be absorbed and more light is reflected back. This data is then shown on the display and stored on the device with the date, roast type, score, and SCAA scale results. The CM-100 has the capacity to store up to 200 results to help track and monitor roasting profiles.
WHOLE BEAN vs. GROUND BEAN
One of the main purposes of the CM-100 is to measure the consistency of the roast and to make sure that the beans are roasted evenly from the outside to the inside. The first step in this analysis of color is to measure a sample of the batch using whole beans. This analyses the light that reflects off the outside of the bean. The second step is to then measure the inside of the bean, which is done by analyzing the roasted beans after they have been ground. Measuring both the inside and the outside of the bean gives the user an accurate reading of the roast as a whole rather than just observing the outside of the bean, which could be dark on the outside, but underdeveloped on the inside. This difference between the outside recording and the inside recording is called the ‘spread’, or the measuring range.
MEASURING RANGE
The measuring range on the CM-100 goes from 5-130, with 5 representing a very dark roast and 130 representing a very light roast. If the spread between the whole bean reading and the ground bean reading is large (e.g. if you had a reading of 50 for the whole bean and 80 for the ground bean), it means that your roast could be underdeveloped, with a much darker outer surface than the inner core of the bean. With this information from the CM-100 color analyzer, roasters can then adjust their roasting variables (time, temperature, airflow, etc.) to dial in a more even and consistent roast profile.
HOW DO I USE IT?
- Make sure your beans are cool before using this tool (heat can bend the light that reflects off the beans, and can affect the refractometer reading).
- Press the Power Button and wait for about a minute for it to ‘warm up’.
- Once it is ready, the display will show the different modes: Measure, History, Calibration, and Setup.
- Remove the tower from the tray and fill the inner tray completely with beans, making sure they are as flat and even as possible in the tray. (For ground beans, the finer the grind, the more accurate the reading will be. And always make sure that your grind size is consistent: if you grind your coffee on an espresso setting one day for a batch, make sure that you’re using that same grind setting the next day.)
- Replace the tower over the tray and the beans.
- Select the ENTER key and select either WHOLE BEAN or GROUND for the type of coffee you are measuring.
- The results will be shown on the display screen, showing a score, a roast type, the date, and the SCAA scale results.
- Back on the home screen, you can use the UP and DOWN arrows to select the different modes. By selecting HISTORY, users can see the previous 200 results which have been stored on the device. After measuring, users can calibrate the device using the calibration weight included in the box.
