A colorimeter probe includes a removable, disposable probe tip with a chamber formed at the outer end of the tip to receive the solution under investigation. In one embodiment of the invention, the probe is in the form of an elongated housing having a light source remote from the probe tip and directs light along a first path toward a reference photocell and simultaneously along another path which extends through the solution chamber and then to a signal cell. In another embodiment of the invention, the light source and sensors are remote from the probe and are optically connected to the probe by means of optical fibers.
