Half-cell reference electrode with glass body and pin-tip connector. Compatible with 8101BNWP, 8101SC ROSS pH half-cell and 8411BN ROSS sodium half-cell electrodes.

• ROSS electrodes avoid the long term drift that other electrodes exhibit (ROSS electrodes drift by less than 0,002 pH per day), so recalibration is minimised
• No sample contamination: ROSS electrodes do not contain any silver or mercury to react with the sample or to clog the electrode junction
• Can be used in samples such as biological media, foodstuffs and pharmaceuticals where trace amount of metals cannot be tolerated
• In order to minimise errors caused by junction potential, users can use a solution that is similar to the sample
• User also has the ability to change filling solutions to minimise contamination when potassium or chloride in the sample are undesirable
