  • Ethernet Communications Port
  • SB Memory Device Port for Data Retrieval
  • Switched 12V Power Output
  • Switched Isolated 5V Power Output
  • LCD Display & Keypad
  • 4 Status LED’s
  • Web Server: Classic Web Interface (HTML) and dEX Enhanced Web Interface (Flash)
  • Rugged Construction: Powder Coated Zinc and Anodized Aluminum
  • Wide Temperature Range: -45°C to 70°C (All M series loggers operate from -30°C to 70°C)
  • Can Be Installed In Class I Div 2 Operational Environments

Sensor Support

In addition, all dataTaker® loggers support the following sensors:

Web Based Software Interface

The web based dEX graphical user interface makes it quick and easy to define basic measurement tasks. dEX 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 runs directly from your web browser and can be accessed either locally or remotely, anywhere that a TCP/IP connection is available including worldwide over the Internet. You can use any of the logger’s communications ports to view dEX. Logged data can also be easily extracted locally via a USB “memory stick”, and all downloaded data can be imported into spreadsheets and data analysis tools.

Integrated Cell Modem

The new “M” series data loggers have integrated HSPA modems that are designed for remote applications. These data loggers have automatic data delivery features to schedule your data to be automatically emailed to your inbox every day, week, month or other time interval. More sophisticated systems can make use of the automatic data delivery features to send logged data to an FTP server. Alarm conditions can also trigger data delivery in addition to sending alarm messages to multiple email addresses or mobile phones.
