How to Measure Superheat. Measuring superheat is relatively simple. First, you’ll need to determine the saturation temperature of the substance you’re working with. For water, this is 100 degrees Celsius. Once you know the saturation temperature, you can measure the temperature of the substance using a thermometer.Actual Line Temp – Sat Temp = Total Superheat. 55°F - 37°F = 18°F. 18°F of Total Superheat > 9°F Target Superheat = Undercharged. Since the actual total superheat measured is higher than the target superheat, we would need to add refrigerant a little at a time until the superheat is the same as the target superheat.

Input these temperatures in a superheat chart, calculation, app, or digital manifold set in order to determine the ...The superheat chart includes target AC superheat for 55°F to 128°F outdoor temperature (DB temperature) and for 50°F to 76°F indoor evaporator temperature (WB temperature). You will find the chart that summarizes all total superheats further on.
