SE 571 Memosens pH Sensor


The design provides high accuracy, stability, speed, and a long life. Through a PTFE ring junction, the reference system is in direct contact with the measured medium. There is low risk of contamination or plugging of the junction. A salt reservoir protects against leaching. A cartridge reference element prevents poisoning of the reference system. Resistant to high pressure.
