DT82E Intelligent Data Logging Solutions for environmental monitoring


The DT82E is a robust, low power data logger featuring USB memory stick support, 18-bit resolution, extensive communications capabilities and built-in display. The dataTaker DT82E's Dual Channel concept allows up to 4 isolated or 6 common referenced analog inputs to be used simultaneously in various combinations. With advanced networking capability (FTP and Web interface), one SDI-12 sensor channel (supporting up to 10 sensors) and switchable 12V regulated output to power sensors, the DT82E is ready to be deployed.

Features

• USB memory for easy data & program transfer
• Dual Channel Isolation Technology
• Serial 'Smart Sensor' port
• User definable allocation of memory size & mode
• Web Interface
• FTP for automatic data transfer
• Modbus for SCADA connection
• 1x SDI-12 port for up to 10 sensors
• Up to 6 Analog (± 30V) sensor inputs
• 8 Flexible Digital channels
