ROSS® pH Electrodes – Experience the Best in pH Measurement

Thermo Scientific Orion^® ROSS pH electrodes offer unmatched benefits that you will not find in any other pH electrode. ROSS electrodes have a proven reputation having set the standard for pH measurement for over 30 years, providing the best accuracy, stability, response and overall performance you will find. Be sure to consider the advantages of a ROSS electrode before selecting your next pH electrode.

Rapid Response and Superior Stability
Compared to conventional electrodes, the proven ROSS reference system exhibits superior stability in measurements, faster response, greater accuracy and precision. Recalibration is minimized when using ROSS electrodes as they are extremely stable over time and avoid the long term drift that other electrodes exhibit. Electrodes drift by less than 0.002 pH per day.

Temperature Response
Refillable ROSS electrodes have a temperature range of 0 to 1000 C and show rapid response and stability even when measuring samples that differ by as much as 500 C. The readings are much more accurate than standard electrodes. ROSS electrodes provide the correct reading within 30 seconds while standard electrodes are still trying to equilibrate after 3 minutes.

Eliminate Sample Contamination
Standard silver chloride electrodes leach metal into the fill solution and eventually into the sample. ROSS electrodes do not contain any silver or mercury to react with the sample or to clog the electrode junction which causes sluggish response or inaccurate readings while also reducing electrode life. ROSS pH electrodes can be used in samples such as biological media, foods, pharmaceuticals or samples that contain TRIS, sulfides or proteins where trace amount of metals can not be tolerated.

Use in Any Application
There are a wide variety of ROSS electrodes to choose from ensuring you have the correct electrode for your application.

ROSS Ultra^® – The Best of the Best!
ROSS Ultra electrodes offer the best stability and drift free measurements of all ROSS electrodes with a reference system designed to provide an enhanced life. We are so confident of it that the warranty is double that of standard ROSS electrodes. Refillable ROSS Ultra electrodes have a 2 year warranty while the low-maintenance triode™ has an 18 month warranty.
The ROSS Ultra line features glass or epoxy electrodes, flat surface and semi-micro designs. ROSS Ultra Triodes include a built-in temperature sensor and provide faster temperature response than other 3-in-1 electrodes.

ROSS
Standard ROSS electrodes provide the same rapid response, accuracy and temperature response as ROSS Ultra electrodes. The reference system provides excellent stability. Their warranty is one year. They are available in a many styles such as glass or epoxy, flat surface, semi-micro, micro, spear tip designs and are refillable.
ROSS Sure-Flow electrodes have a clog-free junction providing reliable measurements after measurements. Simply press down on the cap and flush the junction after measuring your toughest samples and rejuvenate the electrode response. The 8172BNWP ROSS Glass Sure-Flow Electrode is the most reliable and easy to use electrode there is!
