The InPro 8200 turbidity sensor with Kalrez®-FDA window sealing is used for the measurement of turbidity in biotechnological applications - typically biomass growth in fermenters (cell density). The turbidity sensor with Epoxy bonded window is used for the measurement of turbidity in chemical and pharmaceutical process applications - typically crystallization control and solid/liquid separation monitoring. A system is completed with a Trb8300 transmitter and an appropriate sensor housing from the InFit or InTrac family.

The dual optical fiber sensor InPro 8200 combines high resolution at low turbidity ranges with high linearity in the mid turbidity range. Backscattered light technology and the use of fiber optic cables enable a sensor design with uniform, unbroken surface structure. Therefore InPro 8200 sensors are able to meet the toughest demands placed on optical sensors with respect to freedom of fouling and easy cleanability. Trouble-free transfer from laboratory/pilot operation to production level eliminates costs which normally result from required changes of measuring methods. This consistency is possible due to the use of fiber optic technology which enables compact sensor design.
