Extech HD750 Differential Pressure Manometer (5psi)

The HD750 is designed for professionals who need accurate pressure measurement and monitoring in a robust field-ready instrument. With a measurement span of ±5 psi, it captures both gauge and differential pressures over a broad range of units suitable for HVAC, lab, ventilation and industrial applications. The unit offers eleven selectable units of measure including psi, inH₂O, mbar, mmHg, kPa, bar and more, making it adaptable to regional or application-specific preferences. Built-in piezoelectric sensors and quick-disconnect barbed fittings allow for convenient hose connections in the field. It includes advanced functionality such as ZERO/OFFSET correction, Data Hold, MIN/MAX/AVG recording with elapsed time stamps, and a back-lit large LCD display for clear readability in varied lighting. It features a USB PC interface with accompanying software for data acquisition, export and print-ready reporting. Supplied accessories typically include connection hoses, a 9 V battery, AC-adapter, and a hard carry case so the unit is immediately deployable. The enclosure is double-moulded and rugged, suited for demanding environments. In short, the HD750 blends high resolution, flexible units, data acquisition features and rugged build into a compact differential/manometer instrument ready for professional deployment.

Features

• Measurement range: ±5.000 psi (≈±344.7 mbar) with resolution of 0.001 psi for fine differential measurements.

• Eleven selectable units of measure (psi, mbar, kPa, bar, inH₂O, mmHg, ftH₂O, oz/in² etc.) to suit varied measurement frameworks.

• MIN/MAX/AVG recording mode with a time-stamp/elapsed timer to capture critical events and trends.

• ZERO/OFFSET function to set a reference baseline before measurement, enhancing accuracy on site.
