ColorFlex EZ Citrus Spectrophotometer
Easy-to-use. Compact. And Increased Performance. ColorFlex EZ Citrus Spectrophotometer gives you unsurpassed confidence and trust in your outcomes. เครื่องวัดสีวิตามินในน้ำผลไม้
The ColorFlex EZ Citrus measures Citrus Number, Citrus Redness and Citrus Yellowness. These indices were primarily intended to score orange juice concentrate, but in practice have also been used for grapefruit and lemon juices. In addition to the citrus values, the instrument can also measure in terms of the Hunter Lab scale as well as other widely used color scales. Thus the system can also be used to measure the reflected color of virtually any opaque or semi-opaque liquid.
The system comes complete with a sample tube holder, stand, clamp and a calibrated plastic O.J. standard. The instrument has a large, easy-to-read display and a sealed keypad. It requires very little bench space, and is very easy to use. In practice, the juice sample is poured into a test tube or capped tube. The tube is inserted into the instrument tube holder. By pressing one button on the instrument the measurement is made. CN (Citrus Number), CR (Citrus Redness) and CY (Citrus Yellowness) will simultaneously be displayed. The ColorFlex EZ Citrus can be connected to a printer if hard copy data is desired.
