The inoLab® Multi 9420 IDS and 9430 IDS are high performance digital two or three channel benchtop meters. They allow the simultaneous measurement and documentation of up to two (9420) or three (9430) user-defined parameters. The meters can measure pH, ORP, conductivity and dissolved oxygen (optical measurement).

• Simultaneous measurement of two or three equal or different parameters
• Continuous Measurement Control (CMC) for measuring in the optimum pH range
• Digital sensor recognition
• Quality Sensor Control (QSC) benchmarks the current condition of the special IDS pH electrodes
• Automatic digital recording of all sensor data for traceability of all values (GLP-compliant); data transfer via USB interface
• Colour graphic display with CMC, QSC and channel indicator; anti-bacterial keypad

The intelligent digital IDS sensors automatically store their unique serial number and calibration data. They convert sensitive measuring signals into  interference-free data in the sensors, providing superior data integrity. This enables effective evaluation of the sensor quality by means of the Quality Sensor Control (QSC) function.
