Hardness Drops - Test Kit Hach 5B cat.no.145300
This kit contains the necessary materials to conduct multiple tests of the hardness ( in grains per gallon ) of the water.
The "drop count" method is the most accurate available. No guess with a color chart and a wide range test strip.
Each drop added equals 1 Grain ( or 17.1 ppm ), to provide a clear indication of your water hardness.
Includes: Necessary chemicals, test bottle, measuring tube, and instructions.
Can be used to test hardness level as high as 100 grains per gallon ( gpg ).
Use narrow long vial to take "sample" of the water.
Put this "vial" of water sample into the square glass container,
1 small spoon ( included ) of Hardness Reagent powder
Swirl / mix,
Then Add and COUNT the drops of # 3 Tritant Solution
When the sample color changes from pink to blue - Stop.
The resulting number of drops = Grains of Hardness ( GPG )
