Hittade lite nya fakta från tillverkaren: The Mindstream has the capability to measure up to 10 parameters and a calibration reference, simultaneously, using one disk. Conductivity and temperature parameters are not measured from the disc. Different disk types will be available (each measuring up to 10 parameters) for different aquarium needs (i.e., reef, vs cichlid vs freshwater, and so on). The fluorescence technology being used has been adapted from the biotechnology arena and re-tuned for aquarium use. The 12th position (bump) on the disc is a lens and electrode cleaning mechanism. The fluorescence technology being used does not require the use of any additional packets, tabs, powders or other liquid reagents. It is a pure light measurement and the parameter selectivity is controlled by the special fluorescent compound foils designed and optimized for this application.
