COMBI 5000: EC + AM

Activity and EC measurement in one single instrument

The EC + AM 5000 brings together two important functions of salinity measurement: the salinity measurement directly in soils and substrates (activity), as well as the EC measurement in solutions and suspensions. The EC + AM 5000 provides an extended EC-measuring range: from 0-20 mS and from 20 – 200 mS. This makes precise measurements of fertilizer stock solutions possible. Optimal configuration for substrate production, ornamental plants and composting facilities.

Features:
  • 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.
  • 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.
Recommended applications:
  • Nurseries: container plants, particularly if slow-release fertilizers are applied
  • Landscape: golf course greens, sports grounds, etc.
  • Peat production for immediate check during production process
  • Compost plants: to avoid excess of salt concentration in compost soils
  • Communities, local governments: determination of soils charged with chloride after winter period
  • Consultants, advisors, salesmen, etc.
  • Universities, schools, horti-/agricultural educational institutes
  • Pot plant production: control of nutrient solutions (fertilizer mixing systems), stocksolutions
  • Substrate production: salinity control of peat and cocopeat products
  • Hydroponic systems, growing media like rockwool, etc.
  • Laboratory use as universal EC-meter
