Thermo Orion Electrodes
Thermo Scientific Orion Electrode Families and Types
Thermo Scientific Orion pH electrodes have a variety of different families of electrodes available to help with your measurement needs. They are designed to meet all your measurement needs.
Triodes
Combination pH electrode with built-in temperature sensor. Convenience with being able to measure pH and temperature with one electrode. BNC connector for pH measurement and alternative connector for temperature measurement. Compatible with only Thermo Scientific Orion pH meters as temperature connector and temperature element is unique to meter model.
ROSS Ultra® and ROSS® Electrodes
The best electrode available anywhere! Has the fastest response, best accuracy, and reproducibility despite sample composition. Exhibits unmatched response to temperature variations. Double junction reference for complex samples such as biological media, foods, pharmaceuticals, TRIS, sulfides, and proteins. Available in all body styles. ROSS Ultra electrodes have an industry-best warranty.
AquaPro Professional pH Electrodes
Low maintenance polymer-filled double junction electrode. For use in TRIS, sulfides, proteins, and biological media. Has an extended life, fast response, and clog-resistant open junction. Available in the standard, semi-micro, rugged bulb, and flat surface.
Double Junction
Isolated Ag/AgCl reference system which prevents silver from coming in contact with the sample. Great for measuring TRIS buffer, sulfide, and protein samples. Available in standard and micro-body styles.
No Cal®
Unique reference system that provides quick and accurate measurements. Great for measuring TRIS buffers sulfide and protein samples. No calibration is required and accurate to 0.1 pH without calibration. Has the benefit of having a ceramic junction in an epoxy body and also a built-in temperature sensor.
Standard
A large variety of electrodes for a wide range of applications. Includes specialty pH electrodes for unique or challenging pH measurements. Available in most body styles. Microelectrodes are capable of measuring samples as small as 0.5 μL in containers as small as 384 well plates.
KNIpHE®
The pH electrode is housed in a body with a stainless steel blade for measuring meat, cheese, and sludge samples.
Economy or Low-Maintenance
Good performance, valued priced, durable, and low maintenance gel-filled pH electrodes. Available in standard, semi-micro, and flat surface body styles.
Redox/ORP
The ideal choice for measuring the oxidation-reduction potential of samples and performing redox titrations.
ATC Probes
Automatic temperature compensation probes measure sample temperatures and adjust pH measurements by correcting the electrode slope according to the measured temperature.
