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.
