Hydrion Water Hardness Test Kit (packed with two rolls of test paper 0-20 grains per gallon and 10-50 grains per gallon)

描述

The Hydrion Water Hardness Test Kit is packed with two rolls of test papers and two specially calibrated color charts. One roll measures between 0-20 grains per gallon of calcium carbonate. The second roll measures from 10-50 grains per gallon. The color chart has color matches at 0-5-10-20 grains per gallon. A reading of 5 grains per gallon indicates moderately hard water. The second roll of test paper has color chart matches at 10-20-30-50 grains per gallon and is used for testing known hard water sources. The Hydrion Water Hardness Test Kit eliminates the need for expensive laboratory equipment or complicated titration kits. It eliminates the need for technically trained personnel.
