Hardness in feedwater is widely recognized as one of the primary causes of boiler damage. Determining the concentration of hardness ions in incoming water has traditionally required manual testing with chemical indicator solutions. These conventional procedures can be slow, prone to human error, inconsistent between operators, and incapable of providing continuous oversight of hardness breakthrough. Colormetric technology addresses these limitations by automating the entire process — from sample collection and reagent dosing to mixing and measurement — enabling accurate, ongoing monitoring without manual intervention.
