Temperature and Humidity Data Loggers DL2000

for monitoring temperature, humidity, with optional analog input

The Vaisala DL2000 data logger uses highly calibrated temperature and humidity sensors to provide accurate and stable measurement, with an optional analog input channel for other parameters and door contacts. Along with superior accuracy, the DL2000 data loggers record and store data at the point of measurement ensuring that no data is ever lost to power or network downtime. 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.


  • The DL-series data loggers are used with viewLinc software for monitoring, alarming, reporting and vLog for Validation/Mapping GxP Environments.
  • Measurements are traceable to SI units through national metrology institutes (NIST USA, MIKES Finland, or equivalent) or ISO/IEC 17025 accredited calibration laboratories.
  • High accuracy, adjustable time-based digital recording.
  • The Vaisala OPC -DA Server software can be used to integrate Vaisala DL-series data loggers to non-Vaisala systems.

Key benefits

Battery powered with large onboard memory

With autonomous power and recording capacity, data is immune to network and power interruptions, ensuring that records are secure, not modifiable and continuous.

Validate & monitor with same device

The DL-series temperature and humidity data loggers can be used as a networked device for continuous monitoring, or a standalone device for validation/mapping, eliminating the need to purchase multiple devices and calibrations.

Accurate, stable measurements

With superior temperature and humidity sensor stability, you have confidence in the viewLinc system's measurements over a longer calibration interval. Trustworthy data over longer time periods provides lower total cost of ownership of the system.
