Temperature and Humidity Data Logger – DL2000

The Vaisala DL2000 data logger provides highly accurate and stable measurement of humidity and temperature, with an optional analog input channel for other parameters. Together with excellent accuracy, the DL2000 data loggers record and store data at the point of measurement guaranteeing that no data is missed due to power or network downtime.

Key Benefits

Each logger contains a 10 year battery and onboard memory

With autonomous power and recording capacity, data is protected from network and power interruptions, guaranteeing that records are secure, not erasable and uninterrupted.

Validate and monitor with same device

The DL-series data loggers can be used as a networked device for nonstop monitoring, or a standalone device for validation/mapping. This eliminates the need to buy several devices and calibrations.

Accurate, stable measurements

With excellent stability, users can be confident in the system's measurements across a longer calibration interval. Reliable data over longer time periods offers lower total cost of ownership of the system.


Each logger has a 10 year battery and 44,000 sample memory. With autonomous power and recording capacity, data is protected from power and network interruptions, guaranteeing that records are secure and uninterrupted. Completely validatable and engineered for GxP-regulated applications, the loggers are calibrated to global units, ISO/IEC 17025 standards to guarantee cGMP-compliant measurement.

Together with internal RH and temperature sensors, the DL2000 has an input for an external analog device allowing it to track other parameters, including differential pressure, particles, door switches, CO2 or conductivity.


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