A good HVAC technician has a number of specialized tools at their disposal. One such tool is an HVAC gauge. It allows them to measure both air and water pressure in order to determine if the system has enough refrigerant as part of your annual HVAC maintenance.
Old gauges had a needle that pointed to a number to indicate pressure. Today’s gauges are digital and provide a whole host of relevant information at your fingertips. Here are some of the best digital HVAC gauges available right now.
- Fieldpiece. The Fieldpiece SM480V SMAN Digital Manifold is on the expensive side, but it’s well crafted and high quality, making it one of the best digital HVAC gauges. It has four valves and can measure pressure down to the micron. It’s also Wi-Fi-connected for instant data via your computer or other device.
- Testo. A much cheaper option but still one of the best digital HVAC gauges, the Testo 550 Digital Manifold Kit is sturdy and durable and is designed to endure all kinds of weather. It also includes data storage for up to 60 different kinds of refrigerant. Many older models required separate gauges for each refrigerant type. Today’s models can measure levels for all different refrigerants using the same device. The 550 is also Bluetooth-enabled to connect to your phone or tablet.
- CPS. The CPS VG200 Vacuum Gauge is simple but accurate. It doesn’t have the bells and whistles that many of the other models on this list have, but what it has is an accurate gauge that’s easy to read, easy to maintain, and that will last you a long time. For people who are less technologically inclined, this is the model for you.
- Mastercool. The Mastercool 99872-A Blue R134-A Digital Manifold is designed for use in both HVAC systems and automobiles. It can check not only refrigerant levels but oil capacity as well. It comes in a durable plastic case that will stand up to heavy use and last a long time. It’s also user-friendly and easy to read.
