Multi meters Portavo 907 Multi
The only portable device for all Memosens parameters. Also for conventional analog sensors. 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 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 10,000 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.

-High-resolution color graphic display
-Transflective and sunlight readable
-Li-ion battery
-Micro USB port and Paraly SW 112 software
-A sensor quiver protects the sensor from damage and drying out
-The high-performance polymer housing ensures low water absorption and high impact resistance
-Intelligent data logger with 10,000 entries and graphical representation
-Memosens sensors and analog pH sensors can be used on one device (e.g. flat-membrane sensors)
-The mineral glass display is perfectly readable even after years
