Digital manifolds check refrigerant pressure and temperature within AC or Refrigeration systems to evaluate proper working conditions and to troubleshoot for any possible issues. There are numerous configurations in this product category.

Manifold gauge sets, sometimes called HVAC gauges or refrigeration gauges, diagnose and repair refrigerators or cooling systems. They measure both low- and high-refrigerant pressure with either digital or mechanical gauges to troubleshoot issues such as leaks or to help when evacuating and recharging a system.
