PNT 3000 Combi+

PNT 3000 COMBI+: Activity and EC measurement in one single instrument

The PNT 3000 COMBI+ 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 PNT 3000 COMBI+ provides an extended EC-measuring range: from 0-20 mS and from 20 – 200 mS. This makes precise measurements of fertilizer stock solutions possible.

This universal instrument is to be applied in all fields of horticulture!

Recommended applications of the portable PNT 3000 COMBI+:

  • 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
