Characteristics of calibrating liquids for ph and EC meters
These calibration fluids are used to keep running perfectly to your measuring equipment, while guaranteeing durability by efficiently maintaining its useful life, allowing the equipment to continue measuring accurately and effectively. In the case of liquids designed for equipment that measures acidity, there are two versions. One to adjust the pH measurement to 4 and another to calibrate it to a level of 7, which will ensure that you obtain optimal results in the measurement process.
What pH calibration fluids can you buy?
Because calibration fluids are varied, there are different purchasing options for specialized fluids to pH meters, which are:
- pH 4.01 - 300ml
What EC calibration fluids can you buy?
In the case of calibration liquid for EC meters is available:
- EC 1413 - 20ml
- EC 1413 - 300ml

We recommend doing it periodically, and especially before making important decisions about the concentration of your nutrient solution. Those are the moments when a reading error costs you the most.
-
It's the reference conductivity value, 1413 µS/cm, against which the device adjusts its reading. By dipping the probe in a solution of a known value, the meter can correct its deviation.
-
No, this liquid is a conductivity standard and only calibrates EC meters. For pH you'll need the specific pH 4.01 and pH 7.01 solutions.
