# Extech SD750 3-Channel Pressure Datalogger # Extech SD750 3-Channel Pressure Datalogger ## Key Features At A Glance - Triple LCD simultaneously displays all three pressure channels on a single meter - 4-20mA transducer input with readout in 9 selectable units of measure (psi, bar, kPa, mmHg, and more) - Connects to installed transducers up to 5000 psi (4-20mA output) or optional 30/150/300 psi transducers - Date/time-stamped logging to an SD card in Excel-ready format for easy PC transfer - Selectable data sampling rate: 5, 10, 30, 60, 120, 300, 600 seconds, or Auto - Includes six AAA batteries, 2G SD card, universal AC adaptor, three connectors, and mounting bracket - Optional 30, 150, or 300 psi pressure transducers available (sold separately) The Extech SD750 is a 3-Channel Pressure Datalogger that lets a technician monitor and record pressure levels from three sources using one meter instead of three. A large triple LCD shows all three pressure channels simultaneously, and the instrument records its readings to an SD card so they can be moved to a PC for analysis, trending, and archiving. Listed applications for the SD750 include pressure measurements from hydraulic, pneumatic, air compressor, and process gas systems, along with other industrial applications. Because it consolidates three measurement points into a single logging meter, it suits setups where multiple pressure sources must be observed and recorded together rather than monitored on separate instruments.
