InstructionsRinse electrode in distilled (or de-ionised) water, shake off excess water. Immerse electrode in Conductivity Standard for 5 minutes, then calibrate the meter so that it reads the following:
Conductivity meters: Calibrate to 2.76mS/cm or cF27.6
TDS meters: Calibrate to 1800ppm (or as directed)
Once the meter is calibrated it is ready to be used for gauging nutrient concentration. For this consult your nutrient manufacturer for optimum mS / cF (or TDS) that your plants should be grown at.
*Decant a small portion into a small container and discard once used, never return unused solution or place electrodes in this bottle.
Store in a cool dark place.
