Description
The Nu-Calgon 61301 Glycol Refractometer is a precision field instrument designed for HVAC and hydronic system technicians who need a fast, reliable method for measuring glycol concentration levels in heating and cooling systems. Accurate glycol concentration readings are essential for ensuring proper freeze protection and corrosion inhibition — helping protect valuable system components and preventing costly downtime.
Why Use a Glycol Refractometer?
Maintaining the correct glycol-to-water ratio in hydronic systems, chilled water loops, and heat transfer fluid circuits is critical for system performance and longevity. Too little glycol leaves the system vulnerable to freezing; too much reduces heat transfer efficiency. The Nu-Calgon 61301 gives technicians an accurate, on-the-spot reading without the need for lab analysis.
