1. Fieldpiece Job Link Dual Manometer Kit – JL3KM2

The Fieldpiece Job Link® System Dual Port Manometer Probe Kit is one of the best HVAC manometers on the market this 2024. With the ability to take 8 different pressure readings at once while remaining unencumbered by hoses, it’s no wonder why HVACR technicians choose this manometer model as their tool of choice. 

With shortened hoses and sensors able to take measurements between zones, techs won’t have to spend valuable time wrestling or untangling long lengths of silicon tubing. Not to mention, this manometer allows the simultaneous readings of return static, supply static and external static pressure, providing a more holistic understanding of the system’s performance.

This kit includes (2) manometer probes, (2) static pressure probes and hoses, (2) brass screw fittings with an extra hose, (2) slide gas adapters, (4) AAA batteries and a padded case to take measurements and diagnose equipment with ease techs are rarely accustomed to. 

• Price: $200.58
• Manometer Type: Digital
• Units of Measurement: inWC, mmWC, mbar, psi, PA
• Wireless Range: 1000 ft
• Power Source: (2) AAA Batteries

2. Klein Tools Digital Manometer – ET180

If you don’t need all the bells and whistles of the Fieldpiece manometer for double the price, the Kleins Tools ET180 is a quality alternative. It offers the ability to measure pressure from two ports in air or gas systems, making diagnosing and troubleshooting HVAC equipment more efficient and accurate.

A favorite feature is the strong magnet attached to the back of the case, leaving hands free to make adjustments and perform maintenance and repairs. Also, the back-lit display makes it ideal for use in low-lighting conditions that many HVAC techs encounter on the job. The one major complaint about this manometer is it doesn't come with any adapters or fittings. However, those are not so expensive to supplement or as big of a deal when knowing before going into the purchase.

• Price: $109.99
• Manometer Type: Digital
• Units of Measurement: bar, oz/in2, psi, mbar, kPa, inHg, mmHg, kg/cm2, inH2O, ftH20, and cmH2O
• Material: ABS, Stainless Steel  
• Features: Magnetic, Back-Lit Display 
• Power Source: (3) AAA Batteries 
• Battery Life: 150 Hours 
• Weight: 0.42 lbs

3. UEi Test Instruments Dual Differential Manometer – EM152

Another best manometer for HVAC you can’t go wrong with is the UEi Test Instruments EM152 Differential Manometer. It can easily measure differential, positive and negative pressures, perfect for diagnosing issues like blocked or leaky ducts, issues with the damper settings and failing heat exchangers, to name a few. Its back-lit display and magnetic mount also provide technicians with hands-free operation and clear visuals of pressure measurements no matter the lighting situation.

If you were upset to hear that the Klein Tools manometer didn’t come with fittings, you’ll be relieved to know that this one does with (2) silicon tubings, (2) barbed gas valve fittings, a carrying pouch and battery. The reason why this manometer falls behind Klein Tools is because, according to the general consensus, this manometer performs at a slightly lower accuracy rate. However, it still functions with precision worthy of the list of best manometers for HVAC in 2024.

• Price: $113.01
• Manometer Type: Digital
• Units of Measurement: inH2O, psi, bar, mBar, kPa, InHg, mmHg, ozin, FtH2O, cmH2O and kgcm
• Features: Magnetic, Back-Lit Display 
• Power Source: 9V Battery
• Warranty: 1-Year Limited Warranty
