Review on 🔍 HVAC Gas Tester - Digital Dual Port Air Pressure Meter Gauge: Differential Pressure Manometer with 5/16 Inches Diameter Pressure Port, Hti-Xintai by Rob Rogers

The performance and accuracy really impresses this professional HVAC/power engineer, especially at $35. It even includes a data logging feature, which is very useful for intermittent issues like the one I used to have trouble fixing. This thing almost paid for itself before I installed the battery, which another reviewer reported isn't a setup issue if you're careful with the port wiring. Not only can you troubleshoot dozens of aspects of your complex furnace/air conditioner (condensing, variable speed, two-stage cooling), but you can also check for correct natural gas pressure, check when your fancy pleated filter really needs replacing, check how balanced the airflow is in your HVAC system and along with an IR thermometer and a decent kitchen hood and/or toilet extractor even a crude test of the fan door in your home to rule out those pesky drafts. usually contains many analog magnehelic sensors to get the same range/functionality. Is it Dwyer/UEi/Fieldpiece for $150? Of course not. But does it offer 95% return for 20% investment? would anyway! Bravo.
