You are welcome to this guide of the best digital manifold gauges. If you are interested in getting one, you should take the time to go through this guide. With the aid of this guide, you are sure to pick the best digital manifold gauges for you.
What Is a Digita Manifold 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.
TYPES OF DIGITAL MANIFOLD GUAGE
Analog Manifold Gauges
These have two dials that measure the low and high side of the refrigerant. That is why you 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.
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.
DIGITAL MANIFOLD GUAGES BUYER’S GUIDE
Durability
Most digital HVAC gauges are made from metal. They use either aluminum or brass and some are more prone to rust than others. The connector fitting’s build quality should be considered while buying. Plastic fittings usually tend to develop leaks and wear out quickly.
User-friendly
The best HVAC vacuum gauge should be easy to use and connect with quick coupling. It also has the color-coded so you can easily identify the high-pressure red color and low-pressure blue sides. You should also look for a product that has a complete instruction manual.
If your gauge is complicated to use, it will lead to leakages and improper connections that will eventually damage your Air Conditioner unit.
Different Types
There are many fluorinated gases or refrigerant gases that are used in air conditioning units, the most common being R410, R407, R22, and their substitutes such as RS44 / R424A. However, there are many others.
Design of a Gauge
The two most usual reasons for the failure of a mechanical pressure gauge are water condensation and tube vibrations since in colder climates it can freeze and damage the meter cover.
The delicate links, pinions, and pivots of traditional analog pressure gauges are delicate to both vibration and condensation. The lifespan of the pressuring gauge with oil is longer, not only as it has fewer parts that are moving, but also its housing is filled with a viscous oil or glycerin.
This oil filling is beneficial not only because it dampens the leading vibrations, but because it leaves no space for the entry of moist air. Consequently, water cannot accumulate and condense. When using digital pressure gauges, the availability of energy, battery life, ambient temperature/process temperature, humidity, and shock/vibration must be considered.
Should Have Extra Features
When you are going to buy a new digital HVAC gauge, other than hoses and gauges, you should also look for extra features like a can tap and sighting glass. Also, it should have converters such as R-12 or R134A units which you may require.
Adapters
Adapter plays an important role in terms of converting the application of the AC System. If your car has different applications, you should ensure the gauges come with adapters or you will need to buy another gauge for your car’s applicable gauge.
Sighting Glasses
Although sighting glass is not important, it may turn your task easier. Using sighting glass, you can check easily what is going inside. If you HVAC gauge all the latest features which you are looking for, you can skip this facility.
