COMBI 5000 pH + EC

Conductivity meter and pH meter in one device

Simultaneous pH and EC measurement with just one device. The ideal combination for all users of hydroponic growing systems, for consultants and salesman of liquid fertilizers, fertilizer mixers, etc.

  • 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 measured values for different plants.
