Conductivity Meter electrodes invariably become coated with inorganic or organic impurities. This causes a loss of accuracy.
Conductivity (cF, mS) or TDS measurements are used to gauge the total concentration of all salts (i.e., both beneficial and toxic) present in the nutrient solution. They cannot provide any detail on the concentrations of individual nutrients.
Therefore, since a ‘satisfactory’ reading does not imply a balanced nutrient mixture (or provide information on the level of nuisance salts), it is wise to dump every 7-14 days. This is particularly necessary when using salty make-up water because such water causes nuisance chemicals to build up rapidly to toxic levels.
For calibration of Conductivity (EC) and TDS Meters
Calibrates to 2.76mS/cm or cF 27.6 at 25oC (77oF)
Contains Potassium Chloride
Based on international (APHA) standard formula
Please note: CYCO calibration fluids may not be compatible with Hanna Instruments tools which require more precise calibration than regular pens. For Hanna Instruments products, please use their calibration solutions only for hassle-free calibration.
