Testo Vs Fieldpiece : Manifold gauge kits are basically tools you use to gauge the pressure of gases or liquids within an air conditioning system, heat pump system, etc. This is, therefore, a fluid-pressure checking system. They are extremely valuable and one of the very basic tools to have for HVAC technicians or anyone working with heating or cooling systems.
On average, the tool would consist of a high-pressure valve, a low-pressure valve, a high-pressure hose, a low-pressure hose, a centerpiece (manifold), and a center hose. Currently, Manifold systems are available in analog and digital forms. Additionally, certain features, abilities, and valves could be added to make it more versatile.

What are the uses of a digital manifold gauge kit?
So, you already know that the digital manifold gauge kits are used to measure the pressure of fluids in air conditioners and heat pumps. But why do the fluid pressures need to be checked? In the first place, it is useful for determining if there are any leaks. Therefore, it is useful in removing refrigerants or adding small amounts of refrigerants to the system.
Further, knowing the pressure at different points is useful when attempting to recharge, repair, or troubleshoot AC systems. In addition to these basic features, the operation and specifications of a digital manifold gauge can vary widely based on the product and model you select.
A manifold gauge works by working a flow of gas through the unit. Connect the red and blue hoses to HVAC high- and low-pressure points, respectively, in order to take a pressure reading. In addition to vacuuming, the machine can also add refrigerant to a certain level.
Our favorite Digital Manifold gauge sets
There are many types of manifold gauges available. We have selected a few Digital Manifold sets as the most reliable
1.Testo 550 I Digital Manifold Kit for air conditioning
HVAC professionals who are just starting out with their career will benefit greatly from this tool. As a technician, you can still use it to meet all your requirements for a manifold kit since it isn’t too expensive. The product is good enough for nearly everyone who purchases it and responds positively to it because of several factors and features.
This product is very durable and can last you years despite regular use and rough handling. It is designed to withstand harsh conditions. Additionally, it is compact- you will easily be able to hang it or place it wherever you like as you work. In terms of quality, the display is of sufficient quality with a bright white backlight.
A Testo 550 was designed with the capability to store data for up to 60 refrigerants. Due to its two temperature-compensated pressure sensors, it is also extremely accurate. Its controls are simple and intuitive.
There are several modes, including snowflake mode for cooling and flame mode for heat pumps. For beginners, there is an automatic mode. The hard case that comes with the Testo gauges is another thing I appreciate.
2.Testo – 0563 1557 testo 557 I Digital Manifold Kit for air Conditioning
A number of improvements and new features are included in Testo 557 in comparison with Testo 550. Firstly, a 4-valve manifold is more convenient because it allows for the connection of the refrigerant tank (1/4″) and the vacuum pump (3/8″) at the same time minimizing the risk of exposing the system to the atmosphere.
Additionally, Testo 557 has been helium-tested for leakage. You can use it to check air conditioners, heat pumps, and to replace a whole lot of tools that you would otherwise need.
The Testo 557 would be very useful if it had an on-board absolute sensor for measuring and compensating the relative pressure sensors for elevation and pressure. In Testo 550, this feature is also available, but it can only be adjusted manually. In addition, the automatic heat pump feature is quite convenient. Additionally, you can monitor the measurements and data remotely from your phone or tablet using Bluetooth connectivity and the Refrigeration app.
3.Fieldpiece SM480V SMAN Digital Manifold Wireless Data Logging
This digital manifold’s sturdy and durable build is one of the first things that you notice. It is a bit bulkier than Testo products, but that shouldn’t matter much. There are several factors that make the Fieldpiece SM480V Digital manifold one of the best HVAC tools available.
Furthermore, it offers pretty much accurate and precise data for the checking and maintenance of the HVAC system, in addition to its durability systems and offers a lot of advancements against its predecessors as well as other models available in the market. To sum up, it is one of the most advanced and toughest manifolds you can own as an HVAC pro.
