  • differential sensor salt bridge
    When chemicals from challenging applications get inside the sensor reference, chemical reactions can create insoluble salts. These salts clog the reference junction and interrupt the electrical circuit, leading to drifting measurements. Fortunately, our differential pH and ORP sensors can be maintained with the SDS replaceable reference junctions (salt bridges). Simply remove the old salt bridge and insert a new one to restore normal performance to a clogged sensor.

  • pH sensor refill solution
    Refillable glass pH electrodes contain liquid electrolyte solution, which serves to close the electrical circuit in a pH electrode. The electrolyte solution must have electrical contact with the solution being measured. Contact is made via a semipermeable junction, which permits a consistent outflow of liquid electrolyte.  Over time, electrolyte is depleted and should be replaced.

  • Dissolved Oxygen Sensor

    Now Available with optional MODBUS/RS485 Interface

    Our DO6400 series of galvanic dissolved oxygen sensors deliver accurate measurements with very fast response time. Calibration is simple and only requires a single-point air calibration. Sensor directly outputs Millivolt, 4-20mA analog or MODBUS/RS485 digital signal scaled to the sensor range for easy PLC integration.
    • Fast response time for accurate dissolved oxygen monitoring
    • Direct MilliVolt, 4-20mA analog or MODBUS/RS485 digital output signal to integrate with a PLC or other control system
    • Input Voltage Options:
      • 12V DC – MODBUS only
      • 24V DC – 4-20mA & MODBUS
    • Ready for long-term deployment with large electrolyte reservoir
    • One year limited warranty

  • dissolved oxygen sensor
    Our DO1200 galvanic dissolved oxygen sensors measure the oxygen content of water using an electrochemical measurement principle. Built in an economical but durable 12mm epoxy body, these sensors are suitable for portable or benchtop use. The DO1200 can also be installed inline for continuous monitoring applications by upgrading to a PTFE membrane cap. The sensor is compatible with our FC75P 3/4 inch in-line fitting for mounting into 3/4 inch FNPT threaded tees.
    • Galvanic (electrochemical) measurement principle
    • Replaceable membrane cap and fill solution
    • 12mm durable epoxy body
    • For benchtop, portable, or inline use
