The ROSS Ultra Triode™ provides all the benefits that existing ROSS® Ultra electrodes do and exceeds any other pH electrode on the market.  The stability, precision and speed of response of the ROSS Ultra line are combined with a rapid temperature response.  All ROSS electrodes are double junction electrodes that are TRIS compatible and do not contain any mercury like calomel electrodes.

• Unmatched response in samples with varying temperatures.  Stable to 0.01 pH within 30 seconds in 6.86 between 25 ºC and 75 ºC.
• Accuracy within 0.03 pH when using automatic temperature compensation
• Precision of 0.01 pH
• Double junction design prevents sample contamination.  Filling solution can be changed when potassium or chloride in the sample is not desired
• Faster temperature response than other 3-in-1 electrodes
• Compatible in samples with TRIS, proteins and sulfides
• Durable epoxy body
• Two year warranty

ROSS Triode electrodes are available for Thermo Scientific Star™ series, Aplus™ and PerpHecT® meters.
