Prevent scale and corrosion in boilers and cooling towers using Indigo® Water Hardness Test Strips. Fast, reliable checks for calcium and magnesium levels in industrial water systems.

Hardness minerals, mainly calcium and magnesium, are the primary cause of scale deposits in boilers, heat exchangers, and cooling systems. Over time, even moderate hardness levels can reduce heat transfer efficiency, increase energy costs, and promote corrosion under deposits. Indigo® Water Hardness Test Strips provide a rapid, on-site check of CaCO3 concentration so that treatment programs can be adjusted before scale becomes costly.

Details
Discipline / User Key Learning or Application
Engineering Understand scaling mechanisms and apply hardness testing to preventive maintenance programs.
Chemistry Relate Ca2+ and Mg2+ solubility equilibria to scale formation in thermal systems.
Environmental Science Evaluate treatment efficiency and minimize chemical discharge through proper monitoring.
Technician Training Practice quick, field-ready water analysis without lab instrumentation.

Best Practices

  • Test both feed and recirculating water for hardness weekly.
  • Record ppm CaCO3 values to detect softener exhaustion early.
  • Combine with conductivity and pH checks for full water-treatment assessment.
  • Keep spares in toolkits for immediate verification after maintenance.

Specifications
  • The number of strips (50) vial is approximate.
  • Shelf life is 3 years but if bag is properly sealed, they should be good for a minimum of 5 years or more.
  • Strips will degrade if exposed to sunlight and come in a dark bag to prevent this. Do NOT transfer to a clear bag or strips will degrade quickly.
  • Test strips are made in USA & calibrated with NIST standards.

I wanted to find out how hard the water here is, because some water is used with the HVAC condenser on the hottest days. My tap water is very hard - 500PPM was indicated. I knew the water was hard, but not that hard. By contrast, the "5-gallon filtered bottled water" from the self-fill machine at the grocery store showed "0" ppm hardness. It is obvious I will have to install a filter for the condenser water spray so that calcium mineral deposits do not build up on the aluminum coils. The purchase of these test strips was well worth it!
