DT82E - Datalogger for environment (low power consumtion)
Product Description
The DT82E is a robust, low power data logger featuring USBmemory stick support, 18-bit resolution, extensive communicationscapabilities and built-in display. The dataTaker DT82E's DualChannel concept allows up to 4 isolated or 6 common referencedanalog inputs to be used simultaneously in various combinations.With advanced networking capability (FTP and Web interface), oneSDI-12 sensor channel (supporting up to 10 sensors) and switchable12V regulated output to power sensors, the DT82E is ready to bedeployed.

New dEX App for Tablets!
dEX Tablet App for Android and iPad platforms has beenreleased.
Following on from our dEX web-based software, the dEX Appprovides
convenient access to DT8X range loggers via your Tablet.
The dEX App offers users a fully featured version of the dEXweb-based
software for use on a tablet platform. The dEX App has beenlaunched in
conjuntion with our latest firmware release for our DT8X series2 & 3
range.
The new dEX App makes it more convenient that ever to manageyour logger
configurations and monitor your logger data either via yourcorporate
network or directly via your modem logger. The dEX App allowsnumerous
loggers to be setup with their data in reach and accessible withjust a
touch of the screen.
