February 2016, MARIETTA, GA~ These analyzers for Thornton expand our capabilities, allowing us to offer power market customers a low power version of the same high-quality analyzers: 2300Na Sodium Analyzer, 2301Na Sodium Analyzer, and 2800Si Silica Analyzer.

The design of the METTLER TOLEDO Thornton 2300Na Sodium Analyzer is based on extensive instrumentation experience and is optimized to handle these measurement challenges. The electrode is formulated for high selectivity to sodium ion and is complemented by the use of diisopropylamine reagent which has properties to support that selectivity. The 2300Na includes a pH measurement to ensure that proper reagent addition is actually achieved and alarms on low pH. For efficiency, the reference Reliable, automatic, on-line analysis of sodium in water and steam samples helps prevent damaging corrosion and deposits in power plant pure water systems and steam turbines. Chemical and Refining Industries 23 METTLER TOLEDO Best Practice Utilities electrode serves both the sodium and the pH measurements. For calibration, the 2300Na provides unattended automatic calibration. It uses a relatively high concentration standard solution that is easy to prepare and handle. The standard is automatically and consistently diluted to low concentrations for calibration near the range of measurement. Multiple additions of the standard accomplish the known addition method that fully calibrates the analyzer. The METTLER TOLEDO Thornton 2300Na is available in a fully enclosed cabinet for installations on the plant floor or in a more accessible enclosure for cleaner environments.

Features

• Fully automatic, unattended calibration

• Reagent addition confirmation by pH

• Convenient grab sample measurement

• Slow and complete reagent consumption

• Simultaneous display of sodium, adjusted pH, temperature and calibration progress

• Automated electrode conditioning with each calibration

• Four analog outputs for sodium, pH and temperature with choice of scaling

• Choice of two enclosures

The 2800Si Analyzer enables unattended automatic span calibration at a user-configured interval. It uses a relatively high concentration standard solution that is easy to prepare and handle. The standard is automatically and consistently diluted to low concentrations for calibration near the range of measurement. The METTLER TOLEDO Thornton 2800Si analyzer is contained in a fully enclosed cabinet to protect reagent containers and other components from the plant environment.
