dataTaker® DT8x Series Data Loggers

The dataTaker® DT8x series are intelligent data loggers that provides an extensive array of features allowing them to be used across a wide variety of applications. 

The DT8x is a robust, stand alone, low power data logger featuring USB memory stick support, 18 bit resolution, extensive communications capabilities and built-in display. The dataTaker® DT80's Dual Channel concept allows up to 10 isolated or 15 common referenced analog inputs or for the DT85 32 isolated or 48 common referenced analog inputs to be used in many combinations.

With support for multiple SDI-12 sensor networks, Modbus for SCADA systems, FTP and Web interface, 12V regulated output to power sensors, the DT8x is ready to be installed into environmental, industrial and many other types of monitoring projects.
