The conductivity meter COMBI 5000 EC fulfills all demands of a reliable, easy-to-use instrument for all horticultural applications. The high quality sensor is made of platinum-plated electrodes. They feature a very fast response and are completely maintenance-free. The integrated temperature sensor provides an automatic and fast temperature compensation.

The instrument is calibrated before leaving the factory and a re-calibration is basically not required. The measuring range up to 200 mS even allows precise measurements of fertilizer stock solutions.

  • Pot plant production: control of nutrient solutions (fertilizer mixing systems), stock solutions
  • Substrate production: salinity control of peat and cocopeat products
  • Hydroponic systems, growing media like rockwool, etc.
  • Laboratory use as universal EC-meter
  • Easy-to-use: The automatic buffer recognition during calibration also ensures a high level of operating convenience and additional safety.
  • 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.
