RS Hydro supply four different ranges of conductivity standard solutions which are used to calibrate a wide range of conductivity instrumentation. To calibrate instruments the conductivity solutions closest to your measuring range should be selected to provide optimal system accuracy. To achieve optimum accuracy, conductivity solutions are recommended to be used within +/- 5% of 25°C.
Conductivity standard solutions available are 45, 50, 1500 or 4500 µmho/cm. All solutions have a shelf life of 12 months.
