Extech HD700 Differential Pressure Manometer (2psi)

The HD700 is designed as a precision tool for low-range pressure measurement tasks in environments such as HVAC diagnostics, clean-rooms, ventilation systems, and general industrial or laboratory settings. It supports a measurement span of about ±2 psi (≈±13.8 kPa), making it suitable for detecting subtle pressure differences. The unit allows selection from eleven different units of measure (including psi, inH₂O, mmHg, mbar, kPa, bar, kg/cm², ftH₂O, cmH₂O, oz/in² and inHg), providing flexibility for regional or application-specific preferences. Advanced features include MIN/MAX/AVG recording with elapsed time-stamp, Data Hold, Zero/Offset correction, and an auto-power-off function (which can be overridden for continuous monitoring). A large back-lit LCD display ensures readability in varied lighting conditions. It includes a built-in USB PC interface and comes supplied with connection hoses, a 9 V battery, AC adapter, software and a rugged carry-case—ready for immediate deployment. With its combination of resolution, logging capability, unit versatility, and rugged construction, the HD700 is a reliable choice for precise differential pressure measurement and documentation.

Features

• Measurement range of ±2 psi (~±13.8 kPa) with high resolution of 0.001 psi, ideal for low-pressure differential tasks.

• Eleven selectable units of measure (psi, inH₂O, mmHg, mbar, kPa, bar, kg/cm², ftH₂O, cmH₂O, oz/in², inHg) for versatility across applications.

• Dual-input ports (P1 & P2) allowing either gauge or differential measurement mode with quick-disconnect fittings.

• MIN/MAX/AVG recording mode with elapsed timer for trend capture and identifying extreme events.

• Zero/Offset correction function so you can establish a baseline or zero differential before measurement.

• Built-in USB interface and included software for PC connection, data retrieval and export for reporting.

• Large back-lit LCD display and rugged double-moulded housing for field readability and durability.
