The initial goal of the MindStream monitor has been to develop a product that is at least as accurate as current aquarium testing methods such as test kits, titration kits, and photometers, while providing the significant benefits of perpetual, real-time monitoring of numerous parameters. In the long run however, Step Ahead Innovation’s research has indicated that advanced fluorescence and colorimetric sensor technology is capable of achieving much higher levels of accuracy and repeatability.
One aspect of this research is benchmarking the MindStream pH sensor against a $12,500 marine grade Sunburst AFT-pH instrument. Not only is pH critical to maintaining reef tank stability, but it is a key component (along with CO2, temperature, and salinity) in the MindStream system’s calculations of carbonate alkalinity. The Sunburst pH instrument is used in very high precision oceanographic research and represents the “gold standard” in measuring pH.
The chart below shows nearly a full month of actual test data from benchmark testing of the MindStream monitor vs. the Sunburst AFT-pH system. Note these tests were performed in a test aquarium (no fish/coral) and pH levels were initially varied widely to put the sensor through its paces. Even with fast additions of CO2 or alkalinity in the early stages of the test, results from the MindStream monitor track the Sunburst instrument very closely.
The chart below indicates the variance between the two measurements over the same time period. As a point of reference, the National Bureau of Standards can calibrate pH solutions to about +\-0.01 pH, which represents the limits of extreme accuracy in measuring pH (the narrow light blue band on the chart). Experienced reef aquarists know that pH accuracy in the +\-0.1 pH range is sufficient to maintain a healthy tank (the wider darker blue band on the chart).
These results clearly indicate the MindStream monitor is capable of tracking very closely to a sophisticated instrument that claims ultra-high accuracy.
