Superheat on 410a.
It is a clear, colorless, non-toxic and non-irritating liquid. R-410A is a 50:50 blend of R-32 and R-125. The boiling point at atmospheric pressure is -62.9°F. A few of the important principles that make the refrigeration cycle possible are: heat always flows from a warmer to a cooler body.
For superheat measurement, we are only using a low side gauge (blue gauge). The suction line is the bigger vapor line; locate the suction line service port, and screw the blue line from the gauge on there. Here we will measure the lower saturated temperature (40°F in the example above). Attach the clamp-on thermometer to the suction line.
