FAQ

FAQ of  one ways of 4-20mA for Swimming pool  water conductivity  Meter

1. What am I measuring when I measure the conductivity of my solution?
Conductivity is the measurement of the electrolytes in a solution. It is defined as the conductance in a given volume. Conductance is the ability of the solution to conduct electric current.

2. How does temperature affect conductivity readings?
The effect of temperature on conductivity readings depends on the solution being measured. The effect is greatest in low ionic strength (low conductivity) solutions. A general rule to follow is there will be a 2% change (increase)/degree C. This rule can be followed for most aqueous solutions, however if you require a high degree of accuracy, you should consult a chart for the particular solution you are measuring. Organics also have very different temperature curves.

3. Can conductivity be measured in aqueous solutions only?
No, all substances possess some conductive properties. Generally organic compounds (such as benzene, alcohols, and petroleum products) have very low conductivities, while metals have very high conductivities. Measuring the conductivity of highly flammable liquids is very risky.

4. How are conductivity and conductance related?
Conductance is the ability of a solution to conduct electric current, while conductivity is the conductance in a given volume (usually measured in umho/cm).
