Apera DJS-0. 1-C Conductivity Electrode (K=0. 1) is designed for purified water and ultra-pure water conductivity measurements. It's equipped with a glass flow cell, which eliminates impact from CO2 in the air. The high-sensitivity platinum chip sensor design ensures high accuracy in low range conductivity solutions (0 to 200µS/cm). 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.
