remotely, without the refrigerant loss caused by
manifolds and long hoses.
A temperature clamp with minimal thermal mass and a
thermally isolated contact sensor leads to improved
response times, and highly accurate temperature
readings.
These accurate pressure and temperature readings,
paired with the onboard refrigerant library gives you the
ability to view Saturated Temperature, Superheat, and
Subcool calculations in real-time with ease.
With its high accuracy and repeatability, you can
