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!

• 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
