TSI DP-Calc 5825 Micromanometer — Data Logging | Pitot Duct Traverses | HVAC Commissioning
The TSI DP-Calc 5825 is a high-performance micromanometer designed for HVAC commissioning, testing and balancing (TAB), and environmental airflow measurement. It measures differential and static pressure from -15 to +15 in. H₂O (-3,735 to +3,735 Pa), calculates and displays air velocity when used with a pitot tube, and stores over 12,700 samples across 100 test IDs with time and date stamps for full data logging capability.
The 5825 is suited to TAB contractors, commissioning engineers, and building services professionals who need a precise, data-logging pressure instrument for duct traverses, filter and coil pressure drop measurement, fan performance testing, and environmental airflow assessment.
