Description
The Nu-Calgon 4320-W8 Refrigeration Oil Acid Test Kit Phase III is a diagnostic part that is used to identify the amount of acids in refrigeration HVAC system oils. It works by reacting a sample of system oil with special reagents to change color, which is an indication of the acid content that can cause corrosion or damage of the components. The kit is applied to compressor and other lubricated items in the refrigeration system to check the condition of oil and the conditions of the system.
