The model SC450 is designed to measure specific conductivity with contacting electrodes. This method is proven to offer very high measurement accuracy especially in pure and ultra pure water applications. The SC450 a has self tuning pre-amplifier to eliminate the measuring errors that are associated with cabling or with polarization associated with high conductivities and cell fouling. The integrity of the signal across the electrodes is monitored continuously to activate a call for maintenance or a fail message in the rare occasion that cell fouling would cause erratic readings. The standard SC450 covers almost all Conductivity Applications including all special software functions in the standard analyzers to reduce the number of configurations. This results in less inventory and less training needs for users that have multiple Conductivity applications.

Application Note
Overview:

To defray energy costs, many industrial plants have their own boilers to generate steam 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. 

업종:
Overview:

There are a number of suppliers of oil and fat products used for edible purposes. These products include, but are not limited to olive oil, peanut oil, soybean oil, sunflower oil, lard, shortening, butter, and margarine. The raw materials for these products include animal by-products, fleshy fruits (palm and olive), and oilseeds. 

Industry:Food and Beverage

Overview:

Seawater leak detection is the post-condensation water quality management processes. Damage to the ion exchange resin, which deionizes the supplied water, is also monitored during this process, and both of these applications are executed by a conductivity analyzer.
