Seko Sensor Probe for Control

Description

Seko Sensor Probe for Control In water-treatment systems, ensuring that water quality is always at its best – by balancing the variables that impact it – demands the most accurate measuring and analysis devices whether turbidity sensors or pool pH probes.

About Seko Sensor Probe for Control

SEKO’s sensors and probes are built with precision in mind and function in both internal and external water-treatment environments. Monitoring a limit value or building a closed control circuit is easy with our sensors – in an enormous range of measuring applications, from simpler water-treatment tasks requiring pool chlorine sensors to industrial process waters with more stringent requirements.

With a flexible range that’s suitable for liquids of varying concentration, our series of sensors and probes have options designed to comply with water-quality parameters for temperature, pressure, contamination tolerance and chemical resistance. Meanwhile, a virtually zero maintenance requirement contributes to a low total cost of ownership.

Seko sensors and probes cover the following parameters:
  • pH
  • ORP
  • Electrical and inductive conductivity
  • Chlorine and disinfectants
  • Dissolved oxygen
  • Turbidity
  • Flow

The Model of Seko Sensors and Probes

Probes for pH

pH measurements are important in many processes. There is almost none where the pH value does not play a dominant role. All biological processes depend on the activity of enzymes because they show a pH optimum and lose their functionality if the pH is too low or too high. The pH value is measured in most processes using a glass electrode. This pH glass forms a thin gel layer in aqueous solutions that is highly selective to H+ ions. The pH-dependent potential of the gel layer is measured against a built-in reference electrode with a constant potential.

This reference electrode may be a silver wire in contact with solid silver chloride or a calomel electrode. In general, the pH value is a measure of the acidity or the basicity of an aqueous solution.In technical terms, pH is the negative logarithm of the activity of the solvated protons H+. It’s mostly explained as the measure of the proton concentration which is correct for dilute aqueous solutions.
