Increase the accuracy of your readings with a pH sensor that delivers superior performance at varying sample temperatures. Our Thermo Scientific™ Orion™ ROSS Ultra™ Low Maintenance pH/ATC Triode™ combination 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.

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.
