Tightness Test
The 4-valve manifold SM480v also has many features that help as you check for leaks after installations or repairs. Fieldpiece knows how important it is to get things right. With the SM480v, you can know if a drop in pressure during the tightness test is due to a leak in the line set or simply a change in the ambient temperature. Additionally, you can view pressure differential over time and a timer tracks the duration of the test.

Log Data
One of the best features of this tool is how it can store data from your jobs. The 4-valve manifold SM480v can store up to nine different jobs and can log 168 continuous hours of work ‒ that is equal to seven days!

Here at Fieldpiece, we want to help make life for HVACR technicians easier. Visit to learn more about the 4-valve manifold SM480v and other HVACR tools we have to offer.


The Benefits of Using a Refrigerant Weight Scale When Charging HVACR Units

Refrigeration scales play an important role in the HVACR industry. They are used to measure the weight of refrigerant recovered from and charged into a system.

The information is used to determine the amount of refrigerant that should be put into the system is either the manufacturer recommended spec or based on superheat or subcooling calculations. In this process of charging to the correct amount of refrigerant, the weight scale plays one of the following two roles:

  • For charging based on manufacturer spec, the scale confirms the technician adds the correct amount of refrigerant into the system.
  • For charging based on superheat or subcooling, the scale tracks how much refrigerant was needed in order to meet the superheat or subcooling requirements.

The primary benefit of weighing refrigerant using a refrigerant weight scale when charging HVACR systems is to prevent undercharging or overcharging the unit.

Undercharged Unit
An undercharged HVACR system typically occurs because there are leaks in the refrigerant line sets. This results in the refrigerant slowly escaping out of the system. As refrigerant levels decrease, the compressor can overheat causing damage and a shortened lifespan of the compressor or cause the compressor to fail completely. Additionally, an issue like freezing coils can occur.

Overcharged Unit
While less common, overcharging an HVACR system can occur. If an HVACR unit is filled with too much refrigerant, the refrigerant won’t be able to change between liquid to gas and vice versa which leads to inefficient cooling. The compressor will have to work much harder than normal causing higher operating costs and the HVACR system to wear out faster. Overcharging can also lead to liquid refrigerant flooding the compressor causing it to fail, requiring the entire system to be replaced.

Ensuring the HVACR system is properly charged is critical and using a professional refrigerant weight scale is the best way to ensure that. Fieldpiece has scales designed and built for the rigors of HVACR and are the most state-of-the-art in the industry. Visit today to learn more.

What is a HVACR Manifold Gauge?

There are a lot of working parts in a HVACR system that needs to be checked out regularly for maintenance. An important tool that you will need is a HVACR manifold gauge.

A manifold gauge is used to check the pressure of refrigerants in HVACR systems. It is a necessary tool in order to diagnose if the system is correctly charged with refrigerant as well as to help service any issues. A HVACR manifold gauge can be used for many different functions such as checking pressure, adding refrigerant, and determining if there is a leak.

There are different types of manifold gauges and often a HVACR technician may have multiple sets depending on the type of jobs they have. There are 2-valve and 4-valve manifolds. The gauge can be either analog or digital. Many digital gauges now have Bluetooth built-in for connecting to smartphones.

When deciding on a manifold gauge to buy, it is important to ensure the manifold gauge is designed to withstand the rigors of field use including heavy duty casing, reinforced hook, water resistance, and impact resistant screen. Additional features such as data logging and strategically placed thermocouple ports are beneficial.

Refrigeration Tools Every HVACR Technician Should Have

HVACR technicians install, maintain, troubleshoot, and repair heating and cooling systems in both residential and commercial buildings. Your success as an HVACR technician depends on your experience, knowledge, and having the right tools needed for handling any job. Discover some of the top refrigeration tools every HVACR technician should have.

Vacuum pump:  A vacuum pump helps HVACR technicians efficiently remove moisture and other non-condensables from refrigeration and heating units. Vacuum pumps are used to ensure that a refrigeration or air conditioning system is free from contaminants before recharging with refrigerants.

Refrigerant gauge:  Refrigerant gauges are tools used by HVACR technicians to measure refrigerant pressure and make calculations based on the readings received. Digital refrigerant gauges compared to analog ones are extremely helpful for more precise measurements.

Multimeter:  A multimeter is a voltage tester and is a critical safety tool when servicing electrical components of a system. The best multimeters are designed to include all of the tests you use every day – voltage, microamps, capacitance and temperature.

Leak Detector:  While there are multiple ways to identify refrigerant leaks, having an electronic leak detector is recommended as they are more accurate and detect leaks faster.

No matter the job you’re working on as an HVACR technician, having the right tools makes your work easier and more efficient. Visit today to find the ideal HVACR refrigeration tools you need.
