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
