(Determines electrical conductivity of soil)
Direct readout gauge plus a chart which tells soil condition.
Range: 0-10 millimhos; 0-6400 ppm.
Readings in two scales:
millimhos for soil solutions
PPM for hydroponics or water.
For reduced use of excess fertilizers and profit improvement from better crops and larger yields.
