Testo 510 Differential Pressure Manometer gives Aussie HVAC techs fast, reliable static and differential pressure readings for filter checks, duct balancing and gas pressure tests. It’s pocket-sized, temperature-compensated and magnet-mountable, so you can work hands-free and get on with the job—no dramas.

Key Features & Trade Benefits

• Range: 0–100 hPa (≈0–40 inH₂O) – Wide enough for HVAC filter drop and duct static pressure checks without swapping tools.
• Temperature & air-density compensation – More accurate in real-world Aussie conditions (roof cavities, plant rooms).
• 10 selectable units (hPa, Pa, mbar, mmH₂O, inH₂O, inHg, mmHg, psi, m/s, fpm) – Read it how you like, cut conversion muck-around.
• Magnetic back + backlit display – Stick it to steel, read it in low light—bloody good for tight spaces.
• Pitot-tube compatible – Add a pitot to measure air velocity for duct traverses and volume flow.
• Compact, tough, IP40 with ~50 h battery life – Built for site work; less downtime, fewer call-backs.

Why This Manometer Matters

When you’re up on a roof in 40-degree heat chasing a comfort complaint, you don’t want guesswork. A quick probe either side of the filter with the 510 tells you straight away if it’s the filter, the fan speed, or a duct issue. One Brisbane crew told us they shaved twenty minutes off each maintenance visit by using the magnet to mount the meter while they adjusted dampers—too easy.

Pro Tip

Zero the meter in the same spot you’re testing, then connect silicone tubing with tight push-fits. For pitot traverses, aim for straight duct (≥8× diameter downstream of bends) and keep your insertion points consistent. That little bit of discipline saves repeat visits—no worries.

Compatibility & System Info

• Use for: HVAC filter pressure drop, duct static pressure, gas flow/static pressure tests.
• Velocity/volume flow: Supported via compatible Pitot tube and standard silicone tubing.
• Not refrigerant-specific: Works alongside any R32/R410A/R134a system where you’re measuring pressure in air paths, not refrigerant circuits.

Built for Aussie Jobsites

Whether you’re balancing supply branches in Sydney apartments or checking clogged returns after a dusty Brisbane summer, the 510’s backlit display and magnetic mount keep you moving at pace.

FAQs

Q: Can I use the 510 for gas static pressure?
A: Yes—connect to the appliance test port to measure inlet/manifold static pressure. Always follow manufacturer limits.

Q: How do I measure airflow?
A: Fit a Pitot tube, enter duct parameters and traverse the duct to derive velocity (and volume flow). Consider a dedicated velocity kit if you need integrated calculations often, like the Testo 512-1.

Q: Is the 510 the same as the 510i?
A: No. The 510i is a Smart Probe that connects to your phone and has a larger pressure range (−60 to +60 inH₂O / −150 to +150 hPa). The 510 is a pocket meter with onboard display.

Q: Any accessories I should add?
A: Grab a Pitot tube and spare silicone hose. The Fieldpiece 150 mm Pitot Tube (ASP2) pairs well for quick duct checks.
