COMBI 5000: pH + EC + AM

pH, EC and Activity measurement in one device

This configuration provides a combination of the most important measuring parameters: pH, conductivity and activity. Perfect solution for greenhouses, consulting services and educational facilities for practical training.

  • No application errors: The latest microprocessor technology enables automatic sensor detection: each time the probe is changed, the instrument automatically switches to the corresponding measuring mode.
  • Easy-to-use: The automatic buffer recognition during calibration also ensures a high level of operating convenience and additional safety.
  • Fast on: Simply exchange probes during the measurement without a re-start.
  • Save time: Simultaneous measurement of different parameters.
  • Always ready to go: The unit is delivered in a sturdy aluminium case, with all accessories stored safely and within reach.
  • Multilingual: Easy to understand menu is available in three languages: German, English and Russian.
  • Smart: Evaluation via the COMBI 5000 app provides quick and easy storage and interpretation of pH and AM measured values for different plants.
