Cal SOP
pH sensors can be tested using the new SOP calibration procedure with up to 3 calibration points. A further buffer is used as a verification buffer. You can pick and choose the buffer set for each calibration point and also set the sequence.

You can use your own buffer solutions or choose from a list of commercially available buffer sets, e.g., CaliMat, NIST and DIN. For the verification buffer, a maximum permitted deviation (delta pH) is entered.

• The fixed pH calibration procedure reduces potential errors
• Automatic error detection if set limits are exceeded
• Qualified assessment of pH sensors

The Portavo 908 Multi’s professional user management regulates access to the device and the sensor.

• Increased security for configuration, calibration and measurement data
• No unauthorized interventions during the operating cycle
• Up to 4 user profiles can be entered
• Different access rights can be established

Depending on user experience, the role profile can be selectively defined for configuring the device and sensor as well as for calibrating the sensor. The risk of changing settings inadver-tently is clearly minimized in this way.

Memosens sensors can be assigned directly to the Portavo 908 Multi. As such, data saved in the sensor can be consulted, including

• sensor type
• TAG
• group

Unique sensor-to-device assignment reduces potential errors. This ensures that only the right sensors for the selected measuring points are used
