Information

All ROSS pH electrodes have a pH range of 0 to 14, pH precision of 0.01 and temperature range of 0 to 100 °C. ROSS electrodes can be used in samples that contain TRIS, sulfides and proteins since they do not contain silver or mercury. ROSS electrodes incorporate the patented ROSS internal reference system that provides superior measurement stability, faster response, greater accuracy and more reproducible results than conventional electrodes. ROSS electrodes have a double junction reference, so the fill solution can be modified to more closely match the sample composition in high pH, low pH or non-aqueous solutions. ROSS 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 Electrode drift is less than 0.002 pH per day, so recalibration is minimized. All electrodes with a waterproof BNC, BNC or U.S. standard connector have one meter cable lengths, except for the 8107UWMMD and 8157UWMMD electrodes that have a three meter cable length. All electrodes with a screw cap connection require a separate cable. Electrodes with a waterproof BNC connector can be used on any pH meter with a BNC connection. The 800500U ROSS Ultra reference half-cell and 800300 ROSS reference half-cell can be used with the 8101BNWP and 8101SC ROSS pH half-cell electrodes or 8411BN ROSS sodium half-cell electrode.
