Purpose and area of application

  • Express analysis of total mass fraction of milk in water.
  • Analysis of alkaline and acid solutions.
  • Analysis of detergent technological solutions.
  • Separation of mediums: water-milk, water-acid, water-alkaline by predetermined fixed threshold.

Device structure

Measuring element:

  • weight, kg………….1
  • dimensions, mm.........D72x175

Converter:

  • weight, kg……..............1
  • dimensions, mm..........135x60x170

Measurement unit:

  • digital three digit order indication of milk concentration in water, mass % ...in the range of  0-100;
  • analog indication of concentration on the length of incandescent strip in the measured range;
  • indication of the type of measured solution;
  • indication of solution concentration attainment of established threshold values.

Technical characteristics
