Use these unique double-junction electrodes in your most difficult ORP applications. Flat surface does not collect suspended solids--fluid flow across the electrode provides a cleaning action that extends electrode life and improves performance. Annular junction reduces reference cell fouling. Choose either a CPVC housing (max temp 80°>C) or chemical resistant Ryton® housing (max temp 100°>C). Both types have 10-ft cables and can be used at pressures up to 100 psi. BNC connectors match a variety of meters and controllers. Install electrodes in tee fittings--3/4'' NPT(M) thread and 2'' insertion depth.
