Indicator strips "Total water hardness are designed for semi-quantitative determination of the total molar concentration of calcium and magnesium equivalents in drinking, natural and waste waters, as well as for water control in heating networks (boiler rooms, etc.).
Indicator strips "General hardness of water", produced in accordance with TU 2642-007-66948373-2010, are designed for semiquantitative determination of the total molar concentration of calcium and magnesium equivalents in drinking, natural and waste waters, as well as for water control in heating networks (boilers, etc.). This test is fully operational and requires no additional reagents or equipment.
The indicator strips are successfully used in the field, in the laboratory and under industrial conditions.
Scale: < 1.5; > 3.0; > 5.0; > 7.0; > 10.0 °F (mg-eq/L)
