Drop count titration is a simple method to estimate concentrations.

Water hardness test kit for industrial and commercial environments such as water treatment, food and beverage, textile, manufacturing, and other industries.

Drop count titration is a simple method to estimate concentrations. Kit contains two reagents, a measuring tube, a square bottle, and a measuring scoop. Conduct approximately 100 tests per kit. Simple drop-count titration measures hardness as grains per gallon CaCO3 (1 gpg = 17.1 mg/L) with a range of 1-30 gpg.

This kit does not have a blue case--exception in series.
