Portable Memosens pH, conductivity and oxygen analyser

The Knick Portavo series is a range of portable devices for liquid analysis featuring digital Memosens technology. Designed for process engineers, laboratory professionals and field technicians, the Portavo series is designed to provide precision, safety and usability for pH, conductivity and dissolved oxygen measurements.

The Portavo 904X is an IECEX-approved portable meter for Zone 0/1 applications, suitable for hazardous process areas. Each device supports both digital Memosens and traditional analog sensors, for maximum compatibility with existing plant instrumentation. Featuring contactless digital data transfer, a scratch-resistant, sunlight-readable display and a datalogger (5000 points), Portavo helps to enable reliable measurements in harsh process environments.

With intelligent diagnostic tools such as sensor-lifetime monitoring, adaptive calibration timing, and Sensoface health indicators, Portavo instruments are designed to provide repeatable data and minimise downtime.

The USB connectivity and Paraly SW 112 software simplify data management, calibration tracking and documentation, supporting process compliance and quality assurance programs.
