Extech SDL710 Differential Pressure Manometer/Datalogger

The Extech SDL710 Differential Pressure Manometer/Datalogger is designed for low-range pressure measurement and recording in HVAC, building services, and maintenance applications. It measures gauge and differential pressure up to ±2.9 psi (200 mbar) using dual differential inputs with internal sensors, making it suitable for checks such as filter pressure drop, duct pressure, and general system diagnostics.

For documentation, the SDL710 provides both manual and continuous logging options. Users can store up to 99 readings manually, or log continuously to an SD memory card with date/time stamps, saving files in an Excel-compatible format for straightforward download and analysis.

A large backlit LCD supports clear on-site viewing, with practical functions including Max/Min record and recall, data hold, and a zero function for offset correction. Ten selectable units of measure provide flexibility across different job requirements, while auto power off can be disabled for longer logging sessions.
