Aroma of the coffee beans is the valuable perspective that influences the selection procedure of the customers while buying coffee. Aroma of the coffee beans comes up when they are roasted gradually. During the process of roasting, the fragrance and color of coffee beans changes from floral aroma to burnt aroma and the color of the beans also get darker. Hence, white roasting the coffee beans; it is necessary to carefully monitor the color of the coffee beans to maintain the natural and fresh chocolaty aroma.

Purpose of Using Color Checking Instruments

Monitoring this visually can give fluctuated results which are not suitable for the fluent production process. Therefore, making use of color checking instruments is the best process to avoid the subjective method of measurement. This helps to quantify the color of the coffee beans objectively. The best color checking device that can measure the color of coffee beans is TP800 Portable Spectrophotometer.

Technical Expertise of TP800 Portable Spectrophotometer

Testronix’s TP800 Spectrophotometer is designed keeping in mind the advanced principles of LED spectroscopy. The testing machine helps to segregate the lights as per the wavelength interval and adopts the group of the sensor to accurately analyze the color difference and color value of the products. The instrument helps to measure the Delta E value i.e. L*a*b* that depicts the spectral reflectance curve of the color of the sample. This helps to gauge the real factor of color formulas.

Standards of TP800 Portable Spectrophotometer

The instrument offers various color spaces to test the color consistency of different products easily which includes XYZ, Yxz, CIE LAB, CIE LUV, LCh, LAB & WI & YI. These color spaces are introduced as mentioned in the standards like ASTM E313,  CIE/ISO, AATCC, Hunter, and YI – as per ASTM 313, ASTM D1925.

Highlights of Testronix’s TP800 Handheld Spectrophotometer

  • Samples can be observed from two orientations i.e. 2 Degree & 10 Degree.
  • The result of test on the display give following data i.e. Color Difference Value (also in Graphical representation), Spectral Value in graphical format,  Color measurement value,  Color Simulation, PASS/FAIL Result,  time setting, Color Offset,  tolerance prompts,  reverse prompt, restore factory setting, language setting,  and other functions that fulfill the test requirement of almost all applications with all necessary information.
  • It is a very portable device with the dimensions and weight of 90 mm x 77 mm x 230 mm and 600grams respectively.
  • It is fitted with a li-ion battery that can be used 5000 times in 8 hours.
  • The device can store 15000 samples in its memory which explains that it offers storage space.

Testronix offers a broad range of color checking devices to test the color values using highly efficient color formulas and color spaces more efficiently. For more information, visit www.testronixinstruments.com or contact for free advice from our team of specialists.
