389-01-12-55 | Rosemount™ 389 General Purpose pH/ORP Sensor

OverviewThe Rosemount 389 sensors are housed in a molded Tefzel™ body with Viton™ o-rings, making each sensor virtually indestructible and chemically resistant. Complete encapsulation eliminates leakage or high humidity problems traditionally found in other pH/ORP designs. The simplified construction, designed with user convenience in mind does not require electrolyte (KCl) replenishment or any high maintenance troubleshooting procedures.FeaturesA triple junction reference prolongs sensor life and protects against poisoning ions such as ammonia, chlorine, cyanides, and sulfidesEnhanced performance and increased life with cracking resistant glassAvailable with a glass electrode option for high pH applicationsSuperior chemical resistance provided by a rugged Tefzel body with Viton O-ringsThe molded sensor body features 1” MNPT front and rear facing process connections for insertion, submersion, and flow-through applicationsVariopol (VP6) cable connection option, for quick cable-to-sensor release, eliminates cable twistingSMART enabled for pH measurements Ordering Information Model 389 pH/ORP sensor Preamplifier cable 01 Integral preamplifier, 25-ft.
