VitaLink EC Calibration Fluid

Description

VitaLink ESSENTIALS EC Calibration Fluid has a concentration of CF 28 – EC 2.80 – PPM 1820 at 20˚C. Necessary in keeping EC meters accurate.

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. 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. Some plants are more susceptible to EC values out of the optimal range than others. Varies species have different EC thresholds. Both high and low EC’s can increase chances of lower yields.

Regular calibration is necessary to maintain accuracy of your EC meter. If you are using your EC meter daily, you should calibrate it at least once a month. When calibrating, it is necessary that your meter and EC calibration fluid have the same temperature. To achieve this, place them in the same room several hours prior to performing calibration.

How to Calibrate Your EC Meter:

If you can, rinse your pH meter’s probe end off with distilled water. If you don’t have any, clean tap water is fine.

Pour a small amount of calibration fluid into a clean and dry container like a shot glass or small cup. Anything just big enough to submerge to probe into. Don’t use any metal containers. The EC meter will either have an electronic or manual calibration.

If electronic, submerge the probe into the calibration fluid and follow the meters calibration instructions. The meter will confirm when it’s completed.

If manual calibration, it would have come with a small screw driver. Somewhere on the meter, sometimes in the battery compartment, there is a small screw. Submerge the meter’s probe into the calibration fluid. Using the screw driver turn the screw slowly so that the reading on the meter matches the calibration fluid’s value, 2.8 or 280 for example.

Do not throw the used calibration fluid back into the bottle!

Once you’ve calibrated your meter, rinse it with clean water and it will be ready to use. Close the calibration fluid bottle tightly, it will remain accurate for up to 4 weeks after opening. Replace your calibration fluid every 2-3 months.
