About this item

These portable, intuitive conductivity meters, with analogue and digital Memosens® sensor inputs, are suitable for routine measurements. Their versatile functionality, robustness and the large selection of sensors make them the perfect choice 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
Analogue (DIN) sensor input and digital Memosens® input, which allows signals to be digitised and transferred via a non contact connection
Integrated sensor quiver (protective container for sensor) prevents sensor drying out and becoming damaged
Clear glass display is easy to read, even after years of use
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…)

Portavo® 904 also features a data logger with a capacity of 5000 values, micro USB port for PC connection, power supply, Paraly 112 PC software and Li-ion accumulator.
Portavo® 904 ATEX is the only portable analyser with Zone 0/1 ATEX approval. It is explosion-proof and can be used in harzardous areas. The 904 ATEX meter is supplied with appropriate certification. Replacement copies can be found on the Knick website.

Ordering information: All devices (except for the set) are delivered without sensors, which need to be ordered separately.
