Thermo Scientific Orion ROSS Combination pH 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. Operating range is 0 to 100° C. 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, restandardization is minimized. Ceramic junction is standard. Conventional electrodes can leach metal ions into the filling solution and subsequently into the sample.
