Top 10 Best Digital HVAC manifold gauges Reviews from Amazon :(Updated 2018)
#What is a Manifold HVAC Gauge?
A manifold HVAC gauge is an important thing to measure the pressure in an air conditioner or a refrigerator. People use it to determine the presence of leaks. It is also needed to do any form of recharge or evacuation in the machine. The manifold HVAC gauge comes in a set with two different kinds of pressure. One is the low-pressure valve and another one is the high-pressure valve. A compound gauge is also present in the sides of both the valves. The technicians working in the Heating, Ventilation and Air Conditioning generally have such a gauge with them. The manifold gauges come in two types, analog and digital.
The body of a manifold gauge is made from brass or aluminum. Passages are there in the body of the gauges to help it connect to the other manifold parts. Some gauges even have a glass window to let people observe the flow of the refrigerant. The valve wheels come in different colors for easy understanding. The hand wheel of the low side comes with blue and the high side hand wheel has a with red. The high side gauges have a calibration of 0-250 psi and the low side gauges have a calibration of anything between 0 to 100-250 psi. The low side gauge will also have a vacuum measuring capacity of 0-29.9” of vacuum which is approximately 50 microns.
#How Manifold HVAC Gauge Work?
The manifold HVAC Gauges are made in a way that they are easy to use. They are mainly used to measure the unit’s pressure of an air conditioner in a closed system. It helps the technicians in solving problems related to leaks or even the air conditioner in general. The manifold gauge has 3 main components, the low-pressure chamber, the utility chamber, and the high-pressure chamber. All of them have ports that are used for connecting the gauge with the AC through hoses. The low-pressure hose is attached to the low-pressure chamber and the high-pressure hose is connected to the high-pressure chamber.
One can use the utility port for a number of reasons, like to measure vacuum, to connect to the recovery units or even to the port for adding or removing refrigerants. You will see that two handwheels are present at both ends of the tool. This is the main step of using the device as one can open or close the valves to measure adequately. Reading the user manual tells much more about the intricacies of taking a reading.
#What Is a Manifold HVAC Gauge Used for?
A Manifold HVAC Gauge is mainly utilized in the air conditioning industry. Technicians often use it to fix or check central air conditioning systems or even everyday house ACs. But it does have use in the heating, ventilation and refrigeration technicians as well. It helps in transferring AC refrigerant, to check the pressure or to get rid of nitrogen from the system.
#Digital vs. Analog Manifold Gauges: Types of Manifold HVAC Gauge
The HVAC Manifold gauges used to be analogs but now there is a digital model available as well. People are still not used to it and mostly rely on the analog manifold gauges. But let us see the features of both these things.
1.Analog Manifold Gauges:
These have two dials that measure the low and high side of the refrigerant. That is why you really need to know the process well before you can work with it. Technicians learn to read the dials and also convert the reading to make use of them. But this can get tiresome for people who want to use it in their own house or institution. Sometimes even professionals end up misinterpreting the gauges. Some technicians even prefer to carry multiple gauges for analyzing different refrigerants.
2.Digital Manifold Gauges:
The digital manifold gauges have only one display which has everything that a technician will need. It lists the reading and the converted reading is present on the display as well. P/T charts and thermometer is present in the gauge itself. The tool is quite accurate which does away with the requirement of guesswork. But the downside is that digital manifold gauges are more expensive. They are heavier than the analog counterpart. Technicians who aren’t used to the tool have to dedicate their time to read them and to shift to the digital readings.

# How to use Digital HVAC manifold gauges?
As you may have noticed by now, we have included digital manifold gauges reviews in this article. The digital manifolds are emerging to be one of the handiest tools for an AC technician. Using them isn’t that difficult but the technicians will need some time to get learn about it. So, let us see some basic guidelines to use a digital manifold gauge.
- The first step is always to connect the hose according to the color The red side signifies high and the blue side the low. You will connect the red hose to the high-pressure port of the cooling unit with the help of flare fittings. After this, you will connect the blue hose to the low-pressure port present in the cooling unit. It helps in analyzing the vacuum pressure efficiently.
- The waste or vent hose goes in the middle of the gauge. For discharging and venting you will use the black hose and connect it to a recovery bottle for the refrigerant which is important as the refrigerant is bad for the atmosphere.
- One can use other ports to do a number of things like a micron meter gauges or a vacuum pump.
- We will suggest you read the instruction manual that comes with the digital manifold gauge that you have purchased. It will be clear about all the components and the things that you require to do the job.
#Things to consider before buying the Best Digital HVAC Manifold Gauge (Buyer’s Guide):
We have mentioned a lot of things in our review for the HVAC manifold gauges. But as a consumer, you must be sure of the things that you are looking for such a tool. Technicians often carry multiple gauges at the same time to do a proper work. So, buy according to your need rather than going for a cheap or inferior product. Here are some things that you should consider:
- Compatibility: The first thing that you will need to consider is the compatibility with systems. There are several systems like R410A, R22, and R134A etc. So, keep this in mind while you place the order. Do not assume that you can do away with an adapter as at times they do not work.
- Usability: Think about the number of usages that you will get out of the gauge. If you are a professional technician, then you will need a durable and better manifold gauge when compared to a person using it for the AC in their house.
- Budget: Our last point will be the advice on budget. Make sure to think about the budget before purchasing the gauge. These tools are an investment so proceed justly. We will recommend a beginner to get an entry-level product to first develop the habit of readings and to learn the use of the tool well.
- Digital vs Analog: The digital vs analog debate can go on forever. We will further suggest technicians go for a digital manifold gauge because of the positives that we have mentioned in our digital HVAC gauges reviews. But if you feel more comfortable with analog gauges, then that is fine as well.
- Accessories: While buying the set make sure about the things that it comes with accessories. Moreover, it is important as the components will help you to have a complete set rather than a half done one.
Frequently Asked Question for Best Digital HVAC manifold gauges Reviews – FAQs
- Will we be able to tell the valves apart?
Yes, as in a manifold gauge the low-pressure valve is of blue color and the high-pressure valve is red in color. The dimensions are also different to help with the understanding.
- Will we need to calibrate the gauges?
Yes, you will need to calibrate them and the procedure will be there in the user manual or you can take the help of the internet to watch videos.
- Can we use the same manifold gauge for all HVAC systems?
No, the system does differ and you have to have manifold gauges that are compatible with the particular system that you are working with. But often the 4-way manifold gauges support a lot of systems.
Here we are the end of the review for some of the best manifold gauges that are available in the market. We hope that this helps you in choosing an HVAC manifold gauge that works for you. Definitely consult the buying guide to buy a great gauge. The companies that we mentioned are reliable and you will definitely get several uses out of those manifold gauges.
