Product Specification

Portavo 907 Multi Oxy

The all-in-one solution for optical oxygen measurement. Multiparameter device for digital pH, conductivity and oxygen sensors with Memosens technology

The only portable device for all Memosens parameters. The powerful Li-ion battery can be charged in the device via USB. The clear network diagram provides an at-a-glance view of the sensor condition.

The data logger for up to 10,000 entries records measuring point, annotation, sensor ID, sensor serial number (Memosens), primary value, temperature, time stamp and device status.

User-friendly software

Portavo 907 proves that a high level of functionality and easy use are not mutually exclusive. It proceeds step by step through the calibration procedure. Technical terms are clearly explained in the context- sensitive help.
