Increase the accuracy of readings with a pH sensor that delivers superior performance at varying sample temperatures. 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.

• Measure pH and Temperature with one low-maintenance electrode
• Compatible with Orion™ Versa Star™, Orion Star™ A, and Orion™ Dual Star™ meters
• Ideal for pharmaceutical/biopharmaceutical, food manufacturing, academic/government, and environmental applications
• Glass capillary junction
• Isopotential point: 7
• pH range of 0 to 14

Low ionic strength samples, such as clean waters, present a challenge to pH electrode performance.

Complete pH measurements faster, with the assurance of a long, maintenance- free electrode lifetime due to the special long-life gel and innovative capillary glass junction design. Maintain sample integrity, even in TRIS buffers, as these 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 routine sample measurements.

Sluggish response, poor accuracy, and drift are common. These electrodes respond within one minute, providing a stable and accurate reading.
