  • orp calibration solution
    Use this pre-mixed ORP calibration solution for verifying and calibrating ORP sensors.The solution standard is 228mV and is widely used for ORP sensor calibration. Supplied in a pint (16oz) bottle with long term stability.
    • Simple calibration of ORP sensors to known standard
    • Fast response time with all ORP sensors
    • No mixing required - solution is pre-mixed and instantly ready for use
    • One year shelf life guaranteed
  • Our FC75C Flow Cell Kit is an easy and economical means for mounting pH sensors for in-line applications.  Compatible with all 12mm electrodes, including S222CD Light-Duty Online Process pH Sensor. To only purchase the gland, please purchase the FC75P
  • 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.
    • 3.5 M liquid KCl for Sensorex model pH3000
    • 3.5 M liquid KCl/AgCl for Sensorex model pH1400
  • pH Electrode Storage Solution
    Extend the life of your pH and ORP sensors by using the Sensorex pH electrode storage solution. When the sensor is not in use, place the sensor glass measurement area into the storage solution. The pH electrode storage solutions are supplied in pints (473 ml).
  • conductivity calibration solution
    Our TDS / Conductivity Calibration Standards are prepared to NIST (National Institute of Standards and Technology) primary solutions standards. Both Mixed Salts and Single Salt solutions are available. A NIST certificate is also available for a nominal charge. Solutions are supplied in quart bottles (946 ml) and are ready for immediate use. Both the TDS and the conductivity values are listed on the label. Shelf life is guaranteed for a year, and each solution is supplied with a MSDS sheet.
  • pH Sensor Mounting Gland (3/4")
    Our FC75P Mounting Gland are an easy and economical means for mounting pH sensors for in-line applications.  Compatible with all 12mm electrodes, including S222CD Light-Duty Online Process pH Sensor. For Flow Tee See FC75c
  • Transparent Pixel
  • 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
