Chemical Analysis


  • pH – Industrial pH sensors can be used for the measurement of hydrogen ion activity. It is the most widely used liquid analysis measurement and is found in all industries
  • ORP- ORP measurement equipment is used to monitor chemical reactions quantify electron activity or determine the oxidizing or reducing properties of solutions. ORP is a specialized measurement that can follow the progress of a chemical reaction that involves the loss and gain of electrons between species in solution
  • Conductivity – a common measuring technique. Conductivity is a straight forward and reliable way to determine the purity of water, or the concentration of an acid or alkali
  • Chlorine - a chemical widely used throughout industry, especially in water/wastewater treatment. As a common last step of water treatment, chlorination takes place not only to destroy remaining bacteria but to prevent bacteria growth in water pipe systems which deliver clean water to households and industrial locations
  • Dissolved Oxygen – the measurement of dissolved oxygen is especially important in wastewater treatment facilities.  The level of dissolved oxygen determines the life span of micro-organisms in activated sludge basins which break down solid materials. Dissolved oxygen measurement technologies are a benefit to the pharmaceutical and biotechnology industry for measuring oxygen levels in controlled environments for micro-organism growth
  • Turbidity – the process of measuring solids content or suspended solids in wastewater. Most countries have strong regulation regarding getting rid of sludge. Sludge has to be removed from the primary clarifier, recirculated as activated sludge in the biology and separated from the treated water in the secondary clarifier. The process of separating sludge from water is an important cost factor in waste water treatment
  • Chemical Analysis - The reduction or elimination of certain chemicals during the treatment process ensures clean water is introduced back into the environment. This affects all of our rivers, lakes and underground water sources
