Our HI-9815 is unique and we often refer to it as the pH turtle due to its color and shape - but that's where the similarities end. Supplied complete with a double junction pH electrode (and costing no more than if you purchased the electrode on its own), the turtle will turn any computer running windows into a large display real time pH meter.

Simply install the software provided, connect the turtle to the computers serial port, and that's it, your computer monitor can now show a continuously updating table of data and even a real time graph of the pH measurements. An ideal solution where one does not need or want the expense of a bench pH meter, the turtle has proved very popular with the education markets.
