Conductivity Sensors

The conductivity measurement is a very useful and practical method, especially for purposes of quality control. In general, it is a quick and inexpensive way to determine the ionic strength of a solution proportional to the combined effect of all present ions. Therefore, the conductivity has a fundamental role in the control of purity of water in steam generating systems, control of drinking water and quality processes where it is necessary to estimate the total number of ions in a solution. The high reliability, speed and relatively low cost instrumentation conductivity make it a basic parameter in any good monitoring program. Some applications are measured in units of resistivity, which is the inverse of the conductivity. Other applications require the measurement of total dissolved solids (TDS), which is related to the conductivity by a factor dependent on the level and type of present ions. Conductivity measurements are performed in different situations of ion concentration, and may be performed in ultra-pure water, where the values are close to zero, even in very concentrated solution, such as seawater. Choose the model or type of application and discover the conductivity cell that best applies to your needs.
