SSM1:
Super Heat / Sub Cool Meter
Thank you for purchasing the UEi SSM1
Superheat/Subcool Meter. Use the SSM1 to
measure superheat and subcool by direct connec-
tions for temperature and pressure. The SSM1 is
programmed with the most common four refrigerants,
with data from the NIST-Pro refrigeration database
for temperature-pressure values.
Technical Note
Superheat and subcool are the most effective
measures to determine if a system is properly
charged and operating within manufacture
guidelines.
