Disposable liquid chemical sensor system

A disposable sensor system comprising:

• at least one disposable sensor assembly comprising a threaded cap with an index of refraction sensor bonded to the threaded cap, said index of refraction sensor measures a chemical concentration based on a refractive index, said sensor configured to perform data acquisition representing a chemical concentration, the disposable sensor assembly is affixed through a port assembly to a disposable polymeric bag container, the disposable polymeric bag comprising an optical window integrated with the disposable polymeric bag, the sensor assembly coupled to the disposable polymeric bag at an external surface of the optical window;
• an inner surface of the optical window is exposed to the inside of the polymeric bag container;
• said port assembly has an annular outer nipple threaded on the inner diameter and an annular inner nipple threaded on an inner diameter and an outer diameter, said port assembly has an annular inner ring, and the optical window is disposed on said annular inner ring whereby when inner nipple is threaded into the inner threads of annular outer nipple, inner nipple contacts at least said optical window;
• the sensor assembly threads into inner nipple whereby the threads on the outer threaded cap engage the threads on the inner surface of the nipple;
• a first thermal sensor on the optical window and a second thermal sensor on the circuit board of the index of refraction sensor;
• and
• the sensor configured to be coupled to a control and data communications system configured to receive the data representing the chemical concentration from the at least one disposable sensor.
