No more waiting for pH readings to stabilize when measuring samples of varying temperatures. Our Thermo Scientific™ Orion™ ROSS Ultra™ Triode™ pH electrodes combine the stability, precision and speed of response of the ROSS Ultra line with integrated temperature measurement. Orion ROSS electrodes contain no Silver or Silver Chloride and incorporate a double-junction design, which protects the sample from contamination and makes the electrodes compatible with TRIS buffers.
Complete your pH measurements faster. Our ROSS Ultra Triode pH 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. Compatible with Thermo Scientific™ Orion™ Versa Star™, Thermo Scientific™ Orion Star™ A, and Thermo Scientific™ Orion™ Dual Star™ meters, as well as Mettler Toledo™ pH meters.
