The 2085 conductivity cell is a retractable (withdrawable) cell designed for insertion in pipelines and vessels in most industrial applications. The retraction method enables installation without the need for costly bypasses and allows maintenance without process shutdown. The cells are constructed with stainless steel electrodes and are resistant to polarization, requiring virtually no maintenance. The design and method of construction have resulted in a world-class product with an enviable reputation for long life, quality, and reliability.
