Extech SDL720 Differential Pressure Manometer/Datalogger (2000mbar)

The Extech SDL720 Differential Pressure Manometer/Datalogger is designed for measuring and recording mid-range pressure readings in HVAC, building services, and maintenance applications. It measures gauge and differential pressure up to ±29 psi (2000 mbar) using dual differential inputs with internal sensors, making it suitable for duct pressure checks, filter pressure drop, and general system diagnostics.

For documentation, the SDL720 supports both manual and continuous logging. Users can store up to 99 readings manually, or log continuously to an SD memory card with date/time stamps. Logged files can be exported in an Excel-compatible format for straightforward transfer to a PC and further 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, and auto power off can be disabled for longer logging sessions.
