pH Electrodes
Thermo Fisher Scientific offers the widest range of Orion pH electrodes to meet the needs of any application.
View Electrode Application Notes
Endpoint indicators for halide and Karl Fischer titrations.
Products
Automatic temperature compensation probes transmit temperature measurements to the pH meter, which allows the meter to adjust the slope and provide the most accurate, reproducible pH readings.
Products
Low maintenance electrodes with an extended life, fast response, and clog-resistant junction. The double junction reference system prevents silver from coming in contact with the sample, so AquaPro electrodes can be used in samples where metal ions cannot be tolerated.
Products
Products
Low maintenance and refillable electrodes that features an isolated Ag/AgCl reference system, so silver does not make contact with the sample.
Products
Inexpensive, durable, and low maintenance pH electrodes that are the ideal choice for student use and field measurements.
Products
A wide selection of pH electrodes designed to measure samples as small as 0.5 mL.
Products
Specifically designed and tested to provide accurate and reliable pH and temperature measurements when used with Orion PerpHecT digital LogRTM meters. The most accurate pH measurements possible when used with Orion PerpHecT pH meters.
Products
The best of the best! The fastest response, highest accuracy, and best reproducibility that you can get with a pH electrode ? plus a 2 year warranty. ROSS Ultra pH electrodes combine all the benefits of the ROSS line with an extended life expectancy and minimized long-term drift. The ROSS reference offers stable, fast results regardless of
temperature or sample composition.
Products
The ROSS line offers precise pH measurements with unmatched stability,
reliability, and rapid response regardless of temperature or sample
composition. Since ROSS electrodes do not contain silver or mercury, they are well-suited for biological media, food, and pharmaceutical samples where metal ions cannot be tolerated. ROSS Sure-Flow® electrodes have a unique free flowing
reference junction with an easy-to-clean design that assures stable, drift-free
measurements.
Products
Calomel pH electrodes have a mercurous chloride reference and are a value-priced alternative to ROSS pH electrodes for samples in which silver cannot be tolerated.
Products
Non-glass technology is a fast, accurate, and easy-to-maintain alternative to pH sensing glass.
Products
The perfect choice for measuring the oxidation- reduction potential of samples and performing redox titrations.
Products
Half-cell reference electrodes help complete the measuring circuit when using a half-cell sensing electrode. Thermo Fisher Scientific recommends two types of reference electrodes, both include the sleevetype Orion Sure-Flow® reference junction.
Products
Precise pH electrodes that are specialized for unique or difficult applications.
Products
A large variety of value priced pH electrodes for any application.
