Cardy Twin EC Meter
  
The Cardy Twin EC Meter measures the conductivity of soluble salts. Conductivity (or EC) is the measure of total dissolved salts in a solution, the factor that influences a plant's ability to absorb water. In horticultural applications, monitoring of salinity helps manage the effects of soluble salts on plant growth. EC is a meaningful indicator of water quality, soil salinity and fertilizer concentration.

This ultra slim meter features push-button auto-calibration, automatic temperature compensation and a salinity conversion from 0% to 1.1%. Incl.: batteries, case, solution and instructions. Range: 0-199uS/cm, 0-19.0mS/cm; Resolution: 1uS/cm, 0.01mS/cm
