Description
The TSI DP-Calc 5825 Micromanometer is a professional-grade differential pressure meter and duct velocity instrument trusted by Australian HVAC commissioning engineers, test-and-balance (TAB) technicians, and facility managers. Whether you're traversing a duct with a pitot tube, measuring static pressure across an AHU, or logging filter pressure drop over time, the 5825 delivers accurate, repeatable results in a robust field-ready housing.
With onboard data logging for 12,700+ samples across 100 test IDs — each stamped with time and date — the TSI 5825 micromanometer eliminates manual note-taking and makes post-job reporting fast and defensible. It's the go-to differential pressure meter for HVAC professionals across Australia who need a reliable TAB instrument that keeps up with demanding commissioning schedules.
