  • 2-year replacement warranty
  • Builds on the ROSS® technology for greater stability, relability, and renowned accuracy and temperature response
  • Less long term drift saves time from recalibrating
The ROSS Ultra stability gives you ±0.01 pH accuracy even over a long period of time. Using a nonmetallic reference system, the liquid-liquid equilibration occurs almost instantaneously, saving time plus ensuring accurate results. Complex, delicate samples, such as biological media, foods, and pharmaceuticals, measure easily without metallic contamination of the sample or excessive cleaning. ROSS Ultra electrodes are refillable—easily accommodating a change in filling solution for samples sensitive to potassium or chloride ions. Choose ROSS Ultra pH/ATC Triodes for applications requiring built-in temperature compensation.

      The ATC would depend on your pH meter. The ATC is unique to each brand. This probe has a warranty of 2 years.

  • Q:

    Can this electrode be used in flow-through cell at 4 psi pressure? Which pH probes are better for flow-through measurements?
    Asked on 1/19/2012 by Yuri from Toronto, Canada

    1 answer



      This is not rated for anything but atmospheric pressure, and should be calibrated daily. Please contact us at 800-323-4340 and let us know what type of sample you would be using and how long it will be immersed for an ideal recommendation.

  • Q:

    does pH electrode, 8102BNUWP compensate temperature when it measures pH?

    • Staff Reviewer


      No, this probe does not have a temperature element. Also the waterproof BNC connector is compatible with any standard BNC connector both on Orion Star Series meters and competitive meter models. However, it is only guaranteed to be waterproof when used with the Orion Star Series meters.

  • Q:

    Will this electrode also read nitrates?
    Asked on 3/17/2011 by Anonymous

    1 answer



      No, a nitrate ion sensing electrode would be part number: 27502-31. Additional accessories and standards are necessary to use the nitrate electrode. Please contact our technical application specialists for additional assistance (contact information can be found in the "contact us" section on the web page).
