U.S.A. Orion 8157B NMD Tri-Mode pH Filling Electrode

8157BNUMD Detailed Information:

| U.S. Thermo Orion 8157BNUMD Super Ross Tri-Combined pH Electrode

Key Features of Super Ross Electrode

Sample response when the temperature changes; when the electrode is immersed from a 6.86 buffer at 25°C into the same buffer at 75°C, the electrode can stabilize within 0.01 pH in 30 seconds.

When using automatic temperature compensation for electrodes, the accuracy reaches 0.03 pH.

? High reading accuracy up to 0.01 pH

Reliable measurement results with high reproducibility

The electrode features a dual-liquid junction design to minimize sample contamination; replace the electrode filling fluid when chloride or potassium ions are not to be present in the sample.

The temperature response speed of this three-in-one electrode is faster than that of others.

? Measurable TRIS, protein, and sulfide samples

Durable epoxy resin body
