1/4-DIN pH Controller Eutech pH 1000 Controller

Eutech pH 1000 Controller, Oakton InstrumentsSelect from three control modes: on/off, proportional pulse length or proportional pulse frequency.

  • Large dual LCD shows both pH (or mV) and temperature

  • Two set point, two SPDT relay operation- choose from lo/lo, lo/hi, hi/lo or hi/hi control

  • Separate alarm relay

  • 0 to 2000 second time delay adjustment on all relays

  • Separately adjustable high and low set point hysteresis bands

  • 0-20/4-20 mA transmitter/recorder output

  • Push button two-point calibration

  • On-line electrode offset adjustment

  • Hold feature lets you connect flow or level switches to protect your pump

  • Two level password protection

  • LED indicators signal control activities

  • Battery back-up of memory

Control your process with three available control strategies: On/off, proportional pulse length, or proportional pulse frequency. Use proportional control to gradually increase or decrease pump or valve response, depending on the deviation from the set point.

Manually control test relays with the touch of one button. Relays include programmable time delay to minimize false alarms. Hold relay feature lets you connect other controllers, flow switches, or level switches for failsafe operation.

Controller is compatible with a variety of electrodes, including glass and antimony. Symmetrical electrode inputs eliminate electricalnoise problems when used with a solution ground. Connections are made through the two removable terminal strips for easy installation.
