PerpHecT electrodes are the highest quality and most accurate pH electrodes available. PerpHecT electrodes are manufactured to tighter tolerances and offer even greater accuracy and precision than our standard electrodes. When combined with our PerpHecT meters, the most precise pH measurements are possible. The PerpHecT meters have patented LogR™ technology, allowing the user to make temperature compensated pH measurements without the need of a separate ATC probe.

The PerpHecT 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. Because drift is less than 0.002 pH per day, restandardization is minimized.All Thermo Scientific PerpHecT® electrodes have a BNC Connector and 1 m cable.  Cap diameter is 16 mm. PerpHecT LogR^TM temperature measurement and compensation meter specifications are based on the use of PerpHecT and PerpHecT ROSS brand electrodes. Use of other brand electrodes may impact performance.
