These portable, intuitive meters, with analogue and digital Memosens® sensor inputs, are suitable for daily routine pH/°C and mV measurements. Their versatile functionality, robustness and 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 lab stand
- Analogue (DIN) sensor input and digital Memosens® input, which allow signals to be digitised and transferred via a non contact connection
- Integrated sensor quiver (protective container for sensor) prevents sensor dry-out and damage
- Clear, scratch resistant 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 can be used in harzardous areas. It is supplied with relevant certificates. Additional copies can be found on the Knick website.
