Water hardness is considered to be the most common factor in damaging a boiler. The hardness level (ionic concentration) of water inflow to a boiler usually must be checked manually by using chemical reagents known as indicators. Manual measurement using these conventional methods causes such problems as time consumption, personal error or deviation and lack of continuity in monitoring hardness leakage. Colormetry solves all these problems by offering an automatic monitoring system for sample water collection, chemical reagent injection, mixing and evaluation.
