Prototype 2.0 has/will have the following new features:
Hardware: All of the hardware used in the current 2.0 version is the same as the colorimeter with the following two modifications: - LED board: Replace the RGB board with a custom board
- Bandpass filter: Includes an acrylic filter holder with a 430nm bandpass filter
Software: - Custom software for reporting beer color and turbidity
- Beer color (SRM) is calculated from Abs(430nm)*12.7
- Turbidity determined as follows:
- If absorbance at 700nm is less than or equal to 0.0039*Abs(430nm), sample is free of turbidity
- If absorbance at 700nm is greater than 0.0039*Abs(430nm), sample is turbid and should be filtered or centrifuged and re-measured for a more accurate beer color reading
