Vaisala DL1000-1400 is a high-accuracy temperature data logger. Ideal for ultra-low temperature freezers, fridges, cold rooms in regulated environments, the DL1000-1400 temperature logger provides stable, reliable measurements. With a measurement range from -90 °C to +70 °C and stable accuracy at ±0.10°C, the DL1000-1400 series can take up to four inputs for monitoring or mapping temperatures in that range. This series also offers an optional input for door monitoring. 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.
