Multi-parameter meters, handheld, Portavo® 907

These versatile, portable instruments can measure pH, ORP, conductivity and dissolved oxygen (optical). Thanks to their robustness and large selection of suitable sensors, they are suitable for both laboratory and process applications. Waterproof according to IP 66/IP 67.

Reinforced plastic enclosure for rough industrial applications
Integrated cover protects the display and serves as laboratory stand
High resolution colour TFT display is transreflective allowing the display to be read in bright sunlight
Data log function can store up to 10000 values
Digital Memosens® input, which allows signals to be digitised and transferred inductively i.e. via a non-contact connection
Integrated sensor quiver (protective container for sensor) prevents sensor dry-out and damage
Optical oxygen measurements possible
Automatic status check of the device and sensor; evaluation of the sensor data end calibration intervals
Memosens®: All information on sensor life are saved directly on the sensor (history of calibration, operation time, lifetime, sensor wear, SIP cycles…)
