Apera Instruments 2310T-F Conductivity Electrode is designed for high-range conductivity measurement (up to 2, 000 MS/cm, K=10. 0). Equipped with Apera's unique sensor ring coated with platinum black, the electrode provides a stable and accurate measurement in high range conductivity. The accuracy is 1. 5% F. S. Even without calibration, the accuracy can maintain at 10% F. S. Temperature sensor is built in to enable automatic temperature compensation. This electrode is compatible with the following Apera meters: EC800, EC820, PC800, PC820, and EC700. 3Ft cable length. BNC/RCA connector.
