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

Measure pH and Temperature with One Low-Maintenance Electrode

Low ionic strength samples, such as clean waters, present a challenge to pH electrode performance. Sluggish response, poor accuracy and drift are common. The Thermo Scientific Orion ROSS Ultra 8107 Triode pH electrode responds within one minute, proving a stable, accurate reading.

Complete your pH measurements faster. Get long, maintenance-free electrode lifetime with special long-life gel and innovative capillary glass junction design. Maintain sample integrity, even in TRIS buffers; ROSS double junction design electrodes contain no silver, which can bind with biological samples. 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.
