CMTOOL Digital HVAC Gauges with 3 Hoses, 89 Refrigerants, Digital Manifold Gauges Set, Pressure and Temp Test, HVAC Tools with 2 Temperature Clamps, for R134A 1234YF R22 R12 R404A R410A, etc

Good Gauges so far so good

Temp clamp broke after second use. Looking to see if they sell replacements. Otherwise this thing is great. It does all the calculations for you. No more converting psi to temp and subtracting temp etc. love this thing.

These digital gages are not great by any means. You can’t check high and low side pressures at the same time. You have to have one side cut off to get an accurate reading on the other side. There is not a shut off between sides. It you open both sides the high side will just push through and over pressure the low side.

Odd they rate these hoses at 3000PSI (Ha!) yet at 78 PSI they leak at the crimp.The hose itself MAY take that pressure but no point in all that if the crimp joint is garbage!Sent it back and bought same type of unit from another seller and bought a Yellow Jacket hose set!Sadly the yellow Jacket hoses cost more than this manifold set!

I used them one time so far, I like them pretty well, I keep them on hand for backup if needed, I keep them in my backpack with other goodies

facil de usar

Automatic subcooling and superheat calculations!... need i say more other than I wish it included the required batteries... I am like a kid and get very frustrated when the batteries are not included
