Multiparameter meter Portavo 907 Multi Oxy

Mobile multiparameter meter for digital pH/ORP, conductivity and oxygen sensors (Memosens), as well as an interface for an optical oxygen sensor. The powerful Li-ion rechargeable battery can be charged in the device via USB. The clear network diagram provides an at-a-glance view of the sensor condition.

Comprehensive data logger
The following logging types can be selected:
  • Manual logging
  • Time-controlled logging at a fixed interval
  • Signal-controlled logging of measured value and temperature
  • Combined time and signal-controlled logging
  • Threshold-controlled logging with pre-trigger


The data logger for up to 10000 entries records point of measurement, 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.
