pH electrodes, ROSS™, Orion

Supplier: Thermo Orion

The ROSS™ series of electrodes provide readings stable to 0,01 pH in less than 30 seconds, even in the extreme case of samples varying from one another by 50 °C or more. Results are three to five times more precise than those obtained with conventional electrodes. And, because drift is less than 0,002 pH per day, restandardisation is minimised.
