Key Advantages
Triple Sensor Compatibility
Compact design with three PG13.5 sensor ports, enabling multi-parameter liquid analysis from a single assembly for water and wastewater applications.
Stable, Reliable Measurement Geometry
Optimized flow path design ensures consistent, repeatable sensor readings, eliminating measurement fluctuations in varying process conditions.
Built-in Sensor Protection
Siphon-style profile keeps sensors continuously wetted during flow interruptions or plant shutdowns, extending electrode service life.
Simplified Maintenance & Cleaning
Service-friendly removable cover allows quick sensor cleaning and inspection without full disassembly, reducing downtime.
In-Situ Calibration Capability
Calibrate sensors directly while installed in the assembly via the dedicated calibration cap, eliminating the need for removal and re-installation.
