    • Awesome tool
Style: Temperature Kit Pattern Name: Digital Manifold
Bought to test and recharge a newer Mini split but haven't gotten to use for that yet. Used for older conventional R22 unit so far. Simple set up and nice hardshell case. Easy to read display. Decent price for what you get. Used Yellow Jacket hoses and fittings with it.

I did a lot of research when looking into a gauge / manifold for working on HVAC systems. What was important to me was accuracy and simplicity and I'm glad I spent a little extra on this digital manifold vs some of the cheaper analog systems. The biggest benefit of using a system like this is that you can select what you want on the screen, work with different refrigerant types, and it automatically calculates values (like superheat and subcool) automatically if you have the proper gauges hooked up. The wireless sensors (temperature clamps) work in conjunction with the hoses reading temperature / pressure of the high and low side ports. This is what allows you to know the subcool and superheat. There are also places in the case (which is a hard shell case) for other wireless sensors, so I am storing the digital probes and vacuum probe. I ultimately purchased the wireless digital probes alongside this unit because I wanted the flexibility to use a more traditional gauge, or if I wanted a quick reading, just use the digital probes. These are great because they hook up directly to the High / Low ports, and you don't need to use hoses so when testing on an existing system, you are losing next to no refrigerant. The App works as a sort of 'second screen' to the main manifold. You can track and graph readings over time, so you can see a graph of temperature / pressure change as you are working on the system, or when filling. One note, some other reviews mentioned that it eats through batteries - I've not experienced any issues and still using the same batteries from 3+ months ago. Overall, this has been one of the most vital pieces to building a toolkit to work on HVAC systems and at a much more competitive price when compared to other digital manifolds. ... show more

    • Easy to use
Style: Basic Kit Pattern Name: Digital Manifold
The gauge is easy to use and setup. The buttons and fittings are well made and seems like it will last very long. The only bad part is the case which was damaged during delivery. If the case can't withstand delivery, then how can it protect the unit during daily use.

    • Love these gauges, best purchase I’ve made in a long time
Style: Vacum Kit with 3 Hoses Pattern Name: Digital Manifold
My only complaint is that the suction smart probe doesn’t want to connect. I know there’s videos and posts online about other people having the same problem so it would be nice if they fixed that issue. Even with that issue, I’d still give 5 stars. Other than that, these are top notch! Absolutely comparable to, or in my opinion better than, the field piece gauges that are more expensive. I have the app on my phone so I can move around and do what I need to do while checking pressures thru Bluetooth with a click. If you charge using superheat, I HIGHLY recommend this set up plus the thermohygrometer from testo as well. Also Bluetooth, so you can see your wet bulb reading on the indoor from outside, saves me tons of time going in and out, up and down stairs. These gauges will do all of the calculations for you and makes the job so much easier. The Vacuum sensor not working doesn’t bother me one bit honestly, but it may be an issue for someone else so make sure you register your warranty and contact them, I haven’t yet, but I’ve heard they’re easy to deal with. ... show more
