    magnesium
    polyphosphates
    fluorine
    chlorine free
    chlorine residual
    permanganate oxidability
    sulfates
    potassium
    sodium
    manganese
    specific electrical conductivity
    iron (II), (III), total
    aluminum
    copper
    nitrates
    hardness

    calcium
    dry residue/mineralization
    carbonates
    orthophosphates
    ammonia, ammonium
    nitrites
    sulfates
    hydrocarbons
    silicon
    silver

Instructions for water sampling

The minimum volume of water for analysis depends on the selected number of indicators

1

Leave the water to drainfor 5-10 minutes

2

Rinse the bottle and lid with water taken for analysis without using detergents

3

Pour water carefully over the wall of the bottle so that there are no air bubbles in it

4

Fill the bottle with water to the top to keep a minimum of air in the bottle. Close the lid tightly

The laboratory performs analysis of water quality (treated in pool water treatment systems) for compliance with current standards on the following indicators:

    рН
    specific electrical conductivity
    suspended solids
    dry residue / mineralization
    hardness
    permanganate oxidability
    aluminum
    ammonia, ammonium
    iron (II), (III), total
    manganese
    copper
    silver
    polyphosphates
    sulfates
    chlorides
    chlorine free
    chlorine residual
    cyanuric acid

The laboratory tests ion exchange resins on the following indicators:
