Elitech Digital Manifold Gauge 2-Way Valve with Thermometer Clamps for HVAC Systems, LMG-10

I'm not a pro, so this is a review from the point of view of a technically inclined consumer, not an HVAC tech. For what I do, which is maintain and repair the family vehicles and basic troubleshooting of my home AC, this is more than I need, and yet I wouldn't go back to those crappy analog gauges you generally see. I love that it's digital, it's accurate, besides showing the line pressures, it includes tempurature sensor clamps, which are probably more useful for residential systems, but work just fine on an automotive system if you know where to attach them. This allows the device to calculate superheat and subcooling values, a feature pros would utilize. You can select the type of refrigerant in the system, allowing you to use it on R134a one minute, then switch to R4 (or a long list of others I never knew existed) to plug into a completely different system and know that it will still be accurate. It's liquid resistant, and the ports and valve/knob hardware is quality, it makes solid connections, i've had no hint of leaks. The only potential complaint I can see is just that it didn't come with a hose set in the box, so you need to pick those up separately, and figure out which type of end connectors you need for the type of systems you'd use this with (or adapters to switch them). This device has helped me diagnose multiple cars, accurately top off the refrigerant while watching the high and low side pressures and line temps adjust. I was also able to do the same to my aging home system's R4 as it had been a little low.

Very solid and reliable. Readings are spot on and the interface is incredibly easy to use. Best gages for your money hands down. Calculates subcooling and superheat for you. Very durable as well. Have had this manifold for a year now and I couldn't be happier

Gauges work well and very satisfied. Only reason didn't rate five stars is the vacuum reads in negative PSI instead of inches of mercury so you have to know the conversions in your head or have a chart on your phone for reference. Not a big deal but also not a Testo.

I just gave this digital manifold a try today on a residential hvac system and it was really easy to setup and use. I just did a superheat measurement using the pipe temp reader on the suction line and the pressure meter was spot on (Compared it to my analog gauges). The tool feels solid and is not too big, numbers on the screen are large and easy to read. Great case provided stores everything neatly. I wish they could include a temp sensor in the device for dry bulb condenser measurement. Well priced as well, we will see how long it lasts. Recommended.

Nice set of gauges. No longer have to calculate SC, everything is done for you.

They seem to work well. Accuracy between these and analog Mastercool gauges and temp sensors seems decent. However the display lens cracked while they were sitting in their case. They were fine when put away and no impact marks. This makes me worried about longevity. Obviously this is a lower price point, but they may not last a year if that broke when not being used.

Looks like a heavy-duty product compared to its price, works well, and supports most Freon types.

This Elitech Digital Manifold Valve is precise, easy to use, and perfect for HVAC work. Great value and highly recommended!
