    A new interface for using an ISFET (Ion Sensitive Field Effect Transistor) was developed and realized. The advantages of the new design are the small size of the printed circuit board and the low power consumption. This resulted in an electronic circuit small enough to fit in a 25 pins sub-D connector without external power supply. As the circuit is connected to the serial port of the PC, easy interfacing is guaranteed. Furthermore, no hardware calibration is necessary, all calibration can be done by software.
