Thermocouple Data Loggers DL1700

for extreme temperature monitoring

The DL1700 thermocouple data loggers provide accurate temperature data acquisition, remote alarming, and continuous monitoring. The  loggers are ideal for demanding environments that use extreme temperatures, from -240 °C to 1760 °C; applications such as liquid nitrogen (LN2), ovens, sterilization chambers and other extreme temperatures in laboratories and industrial environments. The 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.
