The tool was easy to use. The thermometer clamps are solid. The hoses are fine, probably not the highest end but very decent. I used it to charge my 410a unit and had no issues. The unit itself is solid, the back light helps quite a bit which makes reading the temperatures and pressure on the display very easy.

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.

Not sure if is good or not, I am not an expert but the entire box with the meter inside fell from 3 feet high only once and the screen broke.

Product arrived not working. At first, since this was my first digital gauge, I though perhaps I wasn't using it correctly, so I went back through the manual and carefully checked how to use it. I had occasion recently to give the gauge another try and got the same issues. The low-pressure side only displays E04 where pressure is displayed. The superheat only displays "----" regardless of the actual temperatures. I swapped temp clamps with no change in results. Switching back to manual gauges leaves me to believe that pressures and temp readings may not be accurate. Reached out to the Elitech web site for support, no response after waiting 45 minutes on the "chat" support. I did submit a problem report. Update: 6/21/25 - Got an email with a mpg video attached. The video showed a sequence of button pushes that apparently performed some kind of reset. After performing the action, the gauge seems to be performing correctly. I'm going to check the pressure and temperature accuracy next. For now, I'll upgrade the gauge to three stars.

Item was well packaged and as described. Works great and is a manageable sized operating piece. The gauge readings are digital and clear and no leaks or ill fittings when attached to our compressor and tanks.

I bought these Elitech Gauges this morning on Amazon, they were delivered this afternoon about 5 pm. I put charge hoses on them and decided to test them on my personal AC Units. The High Pressure - Gauge reads about 125 pounds (psig) TOO LOW ! The 1st photo is of the Elitech Gauges connected to my 2.5 ton R410a condenser - with the unit running the Elitech Gauges read 108.5 psig ( low side) and 303.5 on the high pressure side. The 2nd image shows my 4 way mehanical Yellow Jacket Gauges with the "real pressures". As you can see the low ( blue ) gauge is at 116 (8 psig higher than the Junk Elitech sells . The reliable - accurate -Yellow Jacket high side (Red Gauge ) is reading about 425 psig. The proof of the gauges giving a false reading is when the compressor cut out due to excessive head pressure due to being over charged by these defrective inferior made in china Elitech Gauges. I have been a Licensed HVAC Contractor in Arizona, Texas and Florida. I am NATE Certified, Factory Authorized Carrier, Trane and American Standard Dealer with countless hours of training and continued education. I will be happy to testify in court to the fact that these gauges arent worth a dime.
