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.

I bought this wireless digital meter and it has exceeded my expectations. The connection with the app is fast and very intuitive, which makes it much easier to record data and read in real time. The pressure gauges are precise and allow you to work with various coolants without problem.The temperature clamps work well and the hoses feel of good quality. The carrying case is also a nice plus, it keeps everything organized and protected.I recommend it for air conditioning and refrigeration technicians who are looking for a modern, reliable and easy-to-use tool.

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.

Great gauges, plus app display and use of other Bluetooth equipment of the same brand. Accurate Readings. Hoses not that good need to be replaced sooner or later, but the devise itself is great.

Was skeptical at first but I do like them. I am a service tech so use them everyday. I do wish they were a touch wider maybe 1”….. it is a little small but all and all they work great. Def would buy again. The hoses on the other hand…,cheap junkReview update. After having for 2.5 months. Still working as good as day one but now the screen is cracked all the way across. Never stopped them nothing. You be the judge

Beware: 1) this screen cracks for no reason. There are no scuffs, shattering, or impacts to cause it, kept at room temp inside. Yet it starts a crack that then creeps around the perimeter. The display otherwise works ok.2) after using it a few times, the temp clamp readings were way off by 10f & I noticed the pressure readings were not accurate. I therefore don’t trust the measurements which can really mess up my hvac & don’t recommend this product.3) horrible customer service: I contacted elitech via their online form & they asked for pics which I then sent. However i then received no response from them. Then I followed up requesting a replacement per their warranty. Also no response. I tried their chat which no agent comes on, then tried calling & get nobody.I have not used the other functions like vacuum etc.Also not too crazy about the carrying case cuz it requires the refig hoses to be entirely disconnected & store them in the case's sleeve. I therefore don't use the case in order to keep the hoses connected to the guage so that air does not get into the hoses.Also I had to be sure to zero out the pressures before using to prevent inaccurate readings and to prevent an 'eo4' message which will lock up the thing & require a full reset.

This thing for the money and in general it's awesome. It comes with carrying case, hoses, minisplit fittings, and a manual. Easy to register and set up. Size was perfect. Weighty without being heavy. Solid. Hoses weren't the best but after couple seconds of playing with it no problem. No leakage. Arnt best and will replace but usable. Very accurate within 2 percent of our fieldpiece we have at school. Format as well as look and feel of the unit and the app are impressive. Sent my instructor photos and Live footage of my work on a condenser. For half the cost as a field piece or testo I feel I'm cheating the system. Only gripe is I wish I could change the setting for pulling a vacuum from percentage to microns. Pending on accuracy and how percentage works for me might be using a micron gauge. Highly recommended. Let's make testo and fieldpiece bit cheaper with these! Also the app is amazing.UPDATE: screen was found cracked near bottom of screen like others. Coming up on 800 plus the refund decided to go get the testo 558s. Still highly recommend if budget is a issue. Customer service sucks but cracks n all works!
