Description
Description
Certified standard conductivity solution (S51M001) for the calibration of conductivity meters from Hach. Supplied in sealed packaging with a certificate.
Application: For water and wastewater.
Summary of method: Electrolytic conductivity is the movement of ions in a solution, which makes an electrical current and is the reciprocal of the solution resistivity. The ions come from inorganic dissolved solids (e.g., chloride, nitrate, sulfate and phosphate anions and sodium, calcium, magnesium, iron and aluminum cations). Organic material such as oils, phenols, alcohols and sugars do not have sufficient conductivity for a good estimate of the concentration.
Conductivity meters measure the resistance that occurs in an area of the solution that is defined by the physical design of the probe. A voltage is applied between the electrodes, and the voltage decrease caused by the resistance of the solution is used to calculate the conductivity for each centimeter. The basic unit of measure for conductivity is the Siemens (or mho), which is the reciprocal of the ohm. Other common units for aqueous solutions are milliSiemens/cm (10–3 S or mS/cm) and microSiemens/cm (10–6 S or μS/cm).
