Protect your water-steam circuit and ion exchangers with the CA76NA sodium analyzer! If the sodium ion concentration in high-purity feed water or boiler feed water rises, harmful impurities have dissolved in the water. This can cause severe equipment damage and expensive repair costs. The CA76NA performs highly accurate water quality monitoring and quickly detects critical events. The sodium analyzer helps you develop a predictive maintenance strategy and ensure normal power plant operation.
Benefits
Protects expensive plant equipment used in the power industry: the CA76NA sodium analyzer monitors low sodium ion concentrations in the water-steam circuit and detects residues and impurities in the power plant.
Online measurement of sodium ion concentration in the pipe downstream of the vacuum pump provides early warning of condenser leaks.
Low dosing of DIPA reagent and standard solution reduces operating costs.
Precise measurement: independent pH reference electrode with high-precision temperature compensation optimizes pH adjustment.
Optimized investment costs: one analyzer with up to six sampling channels.
Perfectly adapted to process conditions: dedicated sampling channels with freely adjustable measuring intervals.
Applications
In the power industry and utilities, the CA76NA sodium analyzer monitors low sodium ion concentrations:
Indicates water and steam purity in boilers and turbines.
Provides early warning of condenser leaks or ion exchanger failure.
Controls the inlet water quality of power plants using fresh water as the water source.
