Features and benefits

Galvanic’s FPA 4100 family of process photometers enables measurement of the concentration of a wide variety of analytes in both liquid and gas streams. The photonics module can accommodate either UV or visible light sources and has a temperature controlled photo diode block for maximum signal stability. The light source and detectors are coupled to a measurement cell via fiber optic cables.

Delivering the Utmost in Ease-Of-Operation, Precise Measurements, Consistent, Field-Proven Performance and Value

The FPA 4100 controller includes an intuitive user interface with an intrinsically safe, removable keypad, LCD screen, 10 LED indicator lights, and data-loading capability. Rugged and reliable, the systems offer multi-stream-analysis capability, delivering precise continuous measurement with no reagents or compressed gases required. Easy to use and maintain with auto-calibration capability using external standards, auto-zero compensation, and digital optimization of detector gains, the detector electronics are isolated from the process for optimum safety and stability. The FPA 4100 series also enables remote operation and diagnostics via an Ethernet connection.
