DL1700 Thermocouple Data Logger

Thermocouple Data Loggers, NIST Traceable
​ The Vaisala DL1700 series data loggers provide highly accurate temperature data acquisition and are ideal for demanding environments. The data loggers are used with Vaisala's software: either vLog for downloading and analysis, or viewLinc for monitoring and alarming.

  • Ideal for extreme temperatures – from -240 °C to 1760 °C
  • Accepts type J, K, T, E, R and S thermocouples
  • No programming or complicated equations required
  • Highly accurate replacement for bulky data acquisition systems
