Essentials Lab EC / TDS Calibration Solution – 250ml

The EC level of your nutrient solution will influence your plants’ ability to absorb water. If the EC is too high, the roots cannot bring in water and the high concentration of ions can be toxic for the plant.

If EC is too low, the plants may starve from the lack of nutrients.

When calibrating, it is necessary that your EC meter and your calibration fluid have the same temperature.

Regular calibration is necessary to maintain the accuracy of your EC meter!

If you are using your EC meter daily, you should calibrate it at least once a week.

• Essentials Lab CF Calibration Fluid has a concentration of CF 28 – EC 2.80 – PPM 1820 at 20 C
