Mastercool’s A/C System Analyzer is an all-in-one tool that calculates critical information for the air conditioning system as well as diagnoses basic system problems. The LCD display leads the technician through basic tests making service quicker and less complicated. Test results can be saved under a customer and technician name and downloaded for future reference in Excel format. The A/C System Analyzer is able to calculate: actual superheat, subcool, target superheat, temperature split, dry bulb, wet bulb, relative humidity, dew point, air velocity, and airflow volume. Actual superheat and subcool temperatures can be calculated for the following refrigerants: R-22, R-114, R-123, R-124, R-134a, R-141, R-142, R-401a, R-401b, R-404a, R-407a, R-407b, R-407c, R-407d, R-408a, R-409a, R-410a, R-411a, R-411b, R-414a, R-414b, R-417a, and R-507a.
