• 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.

    Product Manuals:



    The channel capacity of the DT80 range of loggers can be increased by using the Channel Expansion Module (CEM20). Each CEM20 connects 20 universal data logging channels to the DT80 range of data loggers.

    A CEM20 connects to one analogue channel of the data logger. This can expand the total channel capacity of the DT80 to 300 analogue inputs (common reference) and the DT85 to an incredible 900 analogue inputs (common reference). Incorporating the same dual isolation technology as the DT80 range data loggers each channel of the CEM20 can be used for two isolated inputs or three common reference inputs.

    dEX Logger Software

    dEX datalogger software is an intuitive graphical interface that allows you to configure your data logger, view real-time data in mimics, trend charts or tables and retrieve your historical data for analysis.

    dEX comes pre-installed on every logger in the DT80 range. The software loads in your web browser so there is no need to install cumbersome applications on your computer. Being browser-based, dEX will work on all major operating systems including Windows, Mac and Linux.
