The 7774/7774D Insertion/Removal Assemblies are designed for industrial processes involving high pressure such as boiler water analysis, demineralization, reverse osmosis, pharmaceutical and chemical production, waste treatment and pulp and paper production.

The ball valve mounting is available with Durafet® (7774D) and Meredian series combination (single-probe) pH or ORP electrodes (7774). For applications requiring chemical resistance or for high-temperature operation, it offers plastic and 316 stainless steel wetted materials. The assembly is easy to operate and maintain and offers a cost-effective way of accurate pH measurement.
