Description
Measure biological media, pharmaceuticals, foods, and more with Thermo Scientific Orion ROSS Ultra Refillable pH/ATC Triode Combination Electrodes. They are ideal for any application where the use of metallic reference electrodes would contaminate the samples. ROSS Ultra pH/ATC electrodes offer more flexibility, accuracy, and precision for your pH measurement needs. With built-in temperature sensors, these electrodes offer a convenient solution for your routine sample measurements.

Unique internal element systemreplaces Ag/AgCl or Hg2Cl2internals with platinum wire and redox-couple filling solution. Double-junction reference cells have porous ceramic or glass fiber outer junction. The design provides stable potential, independent of temperature, and stable readings even when samples vary by 50C (90F) or more. Minimizes drift, stirring effects, clogged junctions; no need for frequent standardization so samples are analyzed faster.
