Conductivity Meters
Measure the EC (electrical conductivity) of leaf sap, as well as water, soil, compost, foliar sprays, etc. The EC of plant sap indicates the level of simple ion uptake in plants. These are those ions that are small and mobile (not yet complexed into larger molecules). Try to keep sap EC between 2,000 - 12,000 µS for optimal g...
Conductivity Meters
Measure the EC (electrical conductivity) of leaf sap, as well as water, soil, compost, foliar sprays, etc. The EC of plant sap indicates the level of simple ion uptake in plants. These are those ions that are small and mobile (not yet complexed into larger molecules). Try to keep sap EC between 2,000 - 12,000 µS for optimal growth on most plants.
Notes on EC meters/probes:
The flat sensor design of the LAQUAtwin EC meter allows it to get a reading with just a few drops of sample making it suitable for plant sap analysis. Although it is possible to get an EC reading on other conductivity meters, the amount of sap required makes them less than ideally suited for that purpose.
All of the conductivity meters from Pike Agri-Lab Supplies have ATC (Auto Temperature Compensation), which removes errors due to changes in temperature.
All EC testers require the use of a standard solution in order to calibrate properly before performing your tests. The LAQUAtwin EC meter includes calibration solution, replenishment standard is available separately.
