The DL4000 data loggers are a simple solution for recording and monitoring pressure, flow, fluid level, pH, electrical properties, moisture and gas concentrations. Ideal for use in standalone or networked data logging applications. The DL-series loggers connect to Vaisala's viewLinc software to provide historical and real-time data, remote alarming, and reporting in compliance with global regulations and standards. The Vaisala OPC-DA Server software can be used to integrate Vaisala DL-series data loggers to non-Vaisala systems. If access to historical measurements is needed, the Vaisala OPC-UA Server can be used to integrate the viewLinc database with non-Vaisala systems.

• Long-life battery and large onboard memory.
• Single and multi-channel models with up to four input channels.
• Easily set scaling and measurement units for recording.
• Time-based digital recording in a range of sample intervals.
• Traceable to SI units through national metrology institutes.
