More About this Item

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.

Use with Orion Star Series pH meters.

  • Q:

    what is the accuracy/reproducibility of the pH 8157BNUMD probe?

    • STAFF EXPERT

      A:

      Here are some of the characteristics of the PH electrode:
      Unmatched response in samples with
      varying temperatures. Stable to 0.01
      pH within 30 seconds in 6.86 buffer
      between 25 °C and 75 °C
      • Accuracy within 0.03 pH when using
      automatic temperature compensation
      • Precision of 0.01 pH
      • Reliable, reproducible results
      • Double junction design prevents sample
      contamination. Filling solution can be
      changed when potassium or chloride in
      the sample is not desired

  • Q:

    Hi,
    I need to now the acceptable slope range that indicates the probe is performing 'good". For example, other probes i use have the following;
    95-105% (good)
    <95% (probe needs a clean)
    >105% change the probe).

    Thanks,
    Martina

  • Q:

    Is this electrode good for measuring nanoparticle (ceramic and metallic) solutions? If not, is there a good electrode that works with Orion SA720 model.

  • Q:

    I need to know the minimum measurable volume with this probe.
    Asked on 6/2/2010 by Aaron from MA

    1 answer

    • STAFF EXPERT

      A:

      The minimum readable volume will depend on the container the sample is in. In order to get a reading there needs to be enough fluid to cover the bulb at the end of the probe (~5mm).
