The measurement of specific conductivity in aqueous solutions is becoming increasingly important for the determination of impurities in water. The accuracy of the measurement is strongly influenced by temperature variations, polarization effects at the surface of the contacting electrodes, cable capacitances, etc. Yokogawa has designed a full range of precision sensors and instruments to cope with these measurements, even under extreme conditions.
These groups of sensors are intended for the low conductivity applications found in the semi-conductor, power, water and pharmaceutical industries and have a convenient and compact design. There are several mounting possibilities one of which is mounting by using a compression gland, giving a simple effective method of direct insertion in process pipework.
Standard these sensors are available in a Stainless Steel or Titanium version fitted with a fixed cable or Variopin connector and include a 3.1 material certificate for the metal wetted parts.
Some of the available types are made from a combination of wetted materials approved by FDA. This makes them ideally suited for the monitoring of pure water systems used in the preparation of injectable solutions. For these applcations, sanitary clamp mountings are available.

United States Pharmacopoeia (USP) is the governing body responsible for issuing guidelines for the pharmaceutical industry. Implementing these guidelines is required for companies that bring drugs to the US market. This means that USP is important to all pharmaceutical companies, period.
To defray energy costs, many industrial plants have their own boilers to generate steam in order to produce a portion of their energy needs. In addition to generating power, the steam may also be used directly in plant processes or indirectly via heat exchangers or steam jacketed vessels.
In the manufacturing process of Pharmaceutical, Chemical and Food & Beverage industries, the cleaning and sterilization of tanks and piping are done with various cleaning solutions, fresh or hot water and steam after manufacturing products. Clean-In-Place (CIP) is the system designed for automatic cleaning and disinfecting.
Ion Exchange is a method for the exchange of ions between two electrolytes or between an electrolyte solution and a complex molecule. In most cases the term is used to denote the processes of purification, separation, and decontamination of aqueous and other ion-containing solutions with solid polymeric or mineralic ion exchangers.
