Thermo Scientific pH Electrodes

Quality electrodes from the industry leader
Works with any pH meter with a BNC connector

 

Thermo Scientific is the leader in pH measurement. Orion pH electrodes are available for all types of samples and all price points. See below for a description of each electrode family. All electrodes feature a BNC connector so can be used on any brand of pH meter with a BNC connector. The "WP" designation indicates the BNC connector is also waterproof and was designed for use on the new Star series of meters from Thermo. These electrodes can still be used on other brands of meters.

ROSS Ultra®: The best of the best. The fastest response, highest accuracy and best reproducibility. Up to a 2-year warranty.

ROSS: Precise pH measurements, unmatched stability, reliability and response time regardless of temperature or sample.

Sure-Flow®: Special flushable junction performs well in dirty, difficult samples. Great for wastewater applications.

Triode: Features a built-in temperature sensor that adjusts pH measurements by correcting the electrode slope based on measured temperature. Triodes are meter series specific due to the temperature element used and the connector.

AquaPro: Low maintenance, double junction electrodes designed for environmental, water and wastewater testing feature an extended life and clog-resistant junction.

Economy: Value-priced, durable and low maintenance.
