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.

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.
