Sodium Monitor Model 8036 SS/8036_5 2 The prevention of damage to the boilers on modern power stations becomes more and more critical as the cost of repairs and out of service plant continually rises. To reduce the effect of boiler tube corrosion and the formation of scale on the inside of the tubes, the levels of impurities in the various parts of the steam/water cycle must be carefully monitored. Sodium ions are normally the most abundant species in solution found in boiler plant, therefore the measurement of sodium provides a valuable indication of the overall purity of the solution....

Sodium Monitor Model 8036 SS/8036_5 3 General Information The ABB 8036 Sodium Monitor is a microprocessor-based instrument which uses a sodium ion selective electrode together with a reference electrode to carry out a potentiometric determination of the sodium ion concentration in the sample. The monitor is designed to meet the exacting standards for sodium measurement of nuclear and fossil-fuelled power stations, providing fast response and high accuracy at both high and low sodium concentration levels. The electronic transmitter unit is housed in a wall-mounted steel case. The liquid...
