The 9900 and 9950-X Multi-Parameter Controllers are field-commissioned with a user-specified combination of inputs, outputs and relays using easy-to-install modules within the base unit. The GF transmitters and controllers support GF Flow, pH/ORP, Conductivity/Resistivity, Salinity, Temperature, Pressure, Level, Dissolved Oxygen and devices that transmit a 4 to 20 mA signal with the use of the 8058 iGo® single channel converter.

Multiple sensor types in one instrument

The sensor types supported include GF Flow, pH/ORP, Conductivity/Resistivity, Salinity, Temperature, Pressure, Level and Dissolved Oxygen.

Optional modules for additional capabilities

Completely flexible, plug-in modules enable the unit to adapt to changing customer needs. Optional modules include the new Modbus as well as the Relay, Direct Conductivity/Resistivity, H COMM, Batch, 4 to 20 mA Output, Single and Dual Channel Direct Conductivity/Resistivity and Modbus Modules. Controllers allow for extended cable lengths and easy wiring.

Compatible with all GF Sensors

Versatility is guaranteed thanks to the multi-parameter support provided for the complete line of GF Flow and analytical sensors, as well as other devices with a 4 to 20 mA current loop output when using the GF iGo module.

Configurable display

The intuitive, user-friendly interface illuminates measurement readings simultaneously via its large display.
