With all these alkalinity monitors and related equipment that are already on the scene, I was wondering if there was any work being done on an actual sensor that did not require titration. I know Seneye has something coming out, but that appears to calculate the carbonate level using CO2 concentration and pH. I did happen on the following links:

They would indicate that a solid state total alkalinity sensor for use in saltwater will be available in the next few years. I can imagine they will be costly, but when some of the alkalinity monitors are retailing at around $500, a $500 sensor doesn't sound so bad if it lasts several yrs without me having to refill anything and can even take continuous measurements.
I'm definitely considering integrating one of these into my RPi controller if the price is right. How many of you will look at purchasing one of these if/when they become available?
