Nutrifield EC calibration solution assists in the measurement of nutrient concentration by ensuring that EC measurement devices provide accurate readings. Electrical conductivity (EC) is a measure of the dissolved ionic particles (nutrients salts) in a solution. The higher the EC reading, the greater the concentration of nutrients.
Directions: To ensure accurate EC readings, calibrate the EC measurement device following the device's usage instructions to the Nutrifield EC 2.77 calibration solution. EC measurement devices should be calibrated weekly or as needed.
