DL-300 Series Data Loggers

YSI’s DL-300 Series are multi-purpose, compact, low-cost measurement and control data loggers. Designed to concentrate data, these entry-level data loggers make data available over varied networks and deliver the data using your preferred protocol. Its small size and low-cost make it ideal for small applications requiring long-term monitoring and control. The DL-310 is longer than the DL-300 and includes an integrated 10/100 Ethernet port and removable terminal connectors.

Compact Design. Big Results .

But that’s just the beginning of what the DL-300 Series has to offer:
 
  • Save money and space with the DL-310’s integrated Ethernet port.
  • Elimate wring headaches through the DL-310’s removable terminal blocks.
  • Setup easily with PC software, USB, and ethernet connectivity. The DL-300 Series is internet ready—Email, FTP, HTTP/Web, TCP.
  • Ease your mind with knowledge of the integral surge and ESD protection.
  • Perform automated monitoring of most hydrological, meteorological, environmental and industrial sensors, on-site or remotely for control and M2M communications.
