The M-BASIC II Agtron Process Analyzer The M-BASIC II is an abridged spectrophotometer designed specifically to address the special requirements associated with evaluating and quantifying the roast of whole bean and ground coffee.
Unlike general "color" instruments, the M-BASIC II operates in the near-infrared energy band where the highest spectral reflectance activity occurs as a function of degree of roast.
Operation The resolution and accuracy of this coffee roast analyzer provides previously unobtainable quantification of the roasting process. With this type of high resolution information, it is now possible to re-define roasting process parameters, greatly improve product consistency, quality and yield.
New Features One of the design priorities of the M-BASIC II was to improve the “analyzer to analyzer” agreement within the M-BASIC II family and over indefinite periods. The results are an inter-instrument correlation of 0.30% and long-term correlation of 0.50%. This is an order of magnitude improvement over previous M-BASIC roast analyzers. A high level of inter-instrument agreement and confidence can be maintained even with analyzers in remote locations.
The many improvements include solid state lamps, improved linearity, and a super-regulated power suplly.
