Control your pH and chemical cost with the Foxcroft FX-421C pH Analyzer with integral compound loop set point controller for food processing, potable water, wastewater, and industrial applications.
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.
The Compound Loop Control Model can adjust pH based on ph and flow. 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.
