FX-421S pH Analyzer and Single Loop Controller

Control your pH and chemical cost with the Foxcroft FX-421-S pH Analyzer with integral single loop controller. It can provide unattended automation to your pH adjustment in food processing, potable water, wastewater, and industrial applications.

With its unique design and microelectronic technology the FX-421-S provides labor savings during installation, start-up, and operation.

The ISFET electrode element is faster to respond, allowing tighter control and stability, requiring less frequent calibration.

Modular construction allows the electrode to be safely removed without disrupting power to the electronics. The electronics provide a 4-20mA output signal as well as a high and low relay. All are sealed in a plastic, weatherproof, corrosion-resistant housing.

TThe Single Loop Control Model can adjust pH based on one variable input. Manually or automatically tune data parameters via the built-in keypad and display. The setup prompts and menus are easy to follow and are available in five languages.

Available controller options include digital input, additional output and alarms, RS485 or Ethernet communication, control via remote computer or SCADA system.
