Top 5 Picks
EDITOR'S CHOICE: Testo 0563 1550 Digital Manifold Kit
And let’s not forget the Bluetooth compatibility. This feature is appearing more and more on today’s market-leading digital manifolds.
It’s easy to see why. The downloadable smartphone app means that the unit can be fully integrated to provide monitoring, reporting, and even invoices via email. The data coming directly from the machine itself.
(That’s a move on from even the most hi-tech units of just a couple of years ago that provided USB support – the entire reporting workflow can now be done wirelessly).
The app can also be used to download new refrigerant profiles from the internet should you need. These can be transferred via Bluetooth to the manifold.
So, we’ve established the technical features on the unit a fantastic, (did I mention that it has the added functionality of leak testing too?), but what about build quality? Does the Testo 0563 hold up there too?
I am happy to say a resounding yes. The robust housing of the manifold features a metal frame around the display, that helps to minimize potential damage after any impact.
Let’s face it, we all know how much these tools can get knocked about either onsite or in the back of the van.
The service case is really well built too.
Other accessories include two temperature clamp probes (0563 has two channel NTC temperature inputs), that are likewise built with durability in mind.
Pros of the Testo 0563 1550 Digital Manifold Kit
Monitoring, report and invoice generation data sent directly to the device for emailing
Large 2-line backlit display for easy readability
Robust construction and case
60 refrigerants included profiles (download more with app)
Includes two temperature clamp probes
The range on the Bluetooth is relatively short
Some customers have experienced missing items when receiving the kit
The Testo 0563 gets our top pick for 2020 because it balances great features with an excellent price-point.
This digital manifold kit really does reperesent good value for money. It’s durable design also means you’ll be using this out in the field for many years to come. A unit that doesn’t disappoint.
While our top pick Testo has great features, if you want the real top range functionality you will need to spend more money.
For that, our recommended unit has to be this premium option from Fieldpiece.
The SM480V is packed with enough features to make even the most discerning refrigerant technician happy.
As the manufacturers state themselves:
“Years of feedback from A/C and refrigeration specialists is combined with Fieldpiece’s laser focus on continuous improvement to bring you the toughest, most advanced digital refrigerant manifold on the market.”
A bold boast, however, there is evidently a lot of truth in this self-evaluation.
Essentially, the unit is built to make the technician’s job easier.
The wireless range of 350 feet is up there as some of the best currently available from any digital manifold, (even models more expensive than this one).
Then there’s the fact this is a 4 valve port micron gauge.
Data Logging is where the unit comes into its own. The SM480V can store up to 9 jobs internally with all data being readily accessible from the manifold.
This information can then be downloaded to your laptop via the USB port. Although, the unit can sustain logs up to 7 days (168 continuous work hours in fact).
Fieldpiece has also included tightness test check as a function; a very useful feature for after repairs and installations.
You can also view pressure differential over time from within the unit; an inbuilt timer will track the duration of each test too.
To avoid potential false positives during testing the unit will compensate for the temperature with an SL temp function.
The build quality is exactly what you would expect from a premium model of this type. The rugged over-molded casing with a reinforced hook and hermetically sealed sight glass means you could drop this out of a 3 story window and still go about your day, completing the job list.
(Don’t try that at home though. 🙂 )
Having said that, a minority of users have had issues with the underside of the unit (close to where the valves are) cracking after long term use.
For those familiar with Fieldpiece digital manifolds, it is worth noting that the SM480V is the direct replacement for the SMAN400 series (SMAN440 and SMAN460).
A major update is a fact you will not need to use the JL2 transmitter for wireless connections, as this new model has full wireless connectivity built-in.
Pros of the Fieldpiece SM480V Digital Manifold
Four-valve manifold with micron gauge
Updated design with built-in wireless function (350 feet range)
Advanced features for professional use
Inbuilt data logging, tightness check tests, etc
Warranty only available if purchased via a registered supplier
If you are looking for an advanced digital manifold, packed with features and built to take a knock (and then some); this is the unit to buy.
Although this is a premium machine designed to make a technician’s life easier, it is still priced competitively. Our top choice premium machine for good reason.
3. BELEY Refrigeration Digital Manifold HVAC System Gauge Set, High-Precision Vacuum Pressure Temperature Leakage Tester Dignostic Meter Kit for Testing Maintaining Air-Conditioner, Refrigerator
The Beley refrigeration digital manifold is a good option and another worthy entry to our top 5.
An inbuilt database gives you access to 89 kinds of refrigerant pressure-evaporation temperature profiles.
The unit is also designed to calculate the subcooling superheat of the system you are testing. It will also provide you with data on the percentage of vacuum measurement as well as pressure leak information. You can also track leak time speeds should that be present.
What’s more, all of this data is accurate. The built-in 32-bit digital processor is designed to provide the highest precision when calculating appropriate measurements. This is a unit you can rely on.
The versatility continues with the Beley when you consider that the unit can measure double pressure at the same time.
It will also provide you with automatic multi-unit pressure conversion. In short, your job is made easier when using a tool such as this.
The readability of data is good too. The large-size liquid crystal display has built-in backlight support; very useful when working in low light conditions.
One minor complaint is that the unit does not feel as robust as some of the other manifolds in our top 5.
True, this is closer in price point to the Mastercool unit reviewed below (our top budget pick); however, the manufacturer of the Beley does seem cheaper.
However, to give you that extra peace of mind after purchasing your new digital manifold, Beley provides a generous 24month after-sales warranty.
Its all very well paying top dollar for an all frills machine that gives you a full range of features; however, what if you are after a more budget-friendly digital manifold that provides the essential functions and that is all.
The user-friendly design is great for technicians looking to efficiently track refrigerant and oil readings on today’s automobiles, (in fact over 55 car manufacturers are catered for with this machine).
Besides essential data logging, this R134a digital manifold will also perform a systems leak check after refrigerant evacuation repair work or installation has been concluded.
As with the other units to make our top 5, the Mastercool is fitted with a clear LCD screen for easy readability. This is also designed in a way that knocks and scrapes will not damage it.
The ABS manifold case is also built with longevity mind, touches such as the rubber boot underside to the case are good to see too.
This is a professional user’s kit, which means you can expect some accessories in the package.
In this case, a set of 3, 72” R134a hoses are included. There’s also a set of manual couplers to get you up and running as you have purchased the item.
The final digital manifold to make our top 5 is this offering from Yellow Jacket. The P51-860 is a mid-priced system that could be seen as a competitor to our top choice from Testo.
The first, most obvious comparison would be that surrounding the Bluetooth connectivity.
Here, essential data can be transmitted to your smartphone for fast and convenient reporting. This is done via the free ManTooth app.
If you prefer to use a laptop, data logging can also be transferred using good old USB ports.
The unit can measure high and low side pressures and temperatures. It will also perform system superheat and subcooling calculations.
Add that to the fact Titan has enabled the manifold to track vapor and liquid saturation temperatures, and you have yourself a machine appropriate for professionals requiring more than just standard operational data.
The P51-860 is a 4-valve manifold unit. It also features an inbuilt processor designed to take accurate measurements for both refrigeration and a/c systems.
All essential data gained can be displayed via the LCD display; however as mentioned above, the Bluetooth connectivity and USB port make transferring this data a breeze.
Pros of the Yellow Jacket P51-860 - Titan Digital Manifold
Bluetooth or USB data transfer
Wide range of measuring functions; high and low side pressures and temperatures etc
Displays vapor and liquid saturation temperatures
Is able to perform superheat and subcooling calculations
Relatively expensive compared to budget-priced models
Does not feature a built-in micron gauge
Overall the P51-860 is a very capable machine packed with a ton or measuring functions.
While some will be overkill for the average user, there is still a lot here designed to make the technician’s life easier.
If these features speak to you, and you have a decent budget for buying your next digital manifold, you should definitely look into purchasing this offering from Titan.
