Review on Elitech LMG-10 HVAC Digital Manifold Gauge with 2-Way Valve and Thermometer Clamps by Michael Daniels

Warning to anyone considering purchasing this sensor set. The fittings on the gauge are 1/4" flare NOT 1/2" acme which is the 134a hose standard. That means you have to buy adapters to use your hoses. Also, the manometer does NOT read the vacuum reading in columns of mercury, but in pounds per square inch. This is impractical as all automotive documentation is in InHg. It's easy to convert to PSI, but I think that's pretty lame.
