The purpose of this project is to improve upon a device that automatically measures pH in order to calculate the alkalinity of seawater using the patented method of reverse gran titration by Dr. Kenneth Hintz and Dr. Christopher Hintz. The current device (Figure 1) which has been designed and implemented by Dr. K. Hintz, obtains an inaccurate reading from the pH electrodes. The task of improvement consists of obtaining an accurate reading of pH with a ±0.02 error margin. The final stage of our project will be incorporated into the current device prototype as shown in figure 1.
