AKMC-1 analyzer is designed for continuous automatic testing of total content of calcium and magnesium salts (total hardness) in water. The Analyzer performs automatic monitoring of water stream for technological processes of water quality control, power generation industry, for environmental monitoring. The analyzer does not consume any chemicals during measurements. AKMC-1 may be incorporated in a complex control system of water hardness test and treatment processes.



Principle of Operation

Is based on potentiometric determination of the total content of calcium and magnesium ions allowing for variation in the flow temperature.


  • Monitoring the operation of water preparation facilities of power plants
  • Monitoring the operation of artesian-well water softening facilities
  • Quality control of feed water for electrical power plants
  • Quality control of turbine condensate of steam power plants
