THERMO 8157BNUMD

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. They have great stability and drift and come with a two-year replacement warranty.

Unique internal element system replaces Ag/AgCl or Hg₂Cl₂ internals with platinum wire and redox-couple filling solution. Double-junction reference cells have porous ceramic or glass fiber outer junction. Design provides stable potential, independent of temperature, and stable readings even when samples vary by 50°C (90°F) or more. Minimizes drift, stirring effects, clogged junctions; no need for frequent standardization so samples are analyzed faster.
