Trotec Professional Datalogger DL200D

Professional data logger DL200D

In addition to the standard climate data, such as temperature and humidity, the professional data logger DL 200 D has the function to measure the relative and absolute air pressure.


In addition to climate information on air temperature and humidity, the integrated sensor technology of the DL200D also detect the current air pressure values.

Thanks to its flexible combination of real time data display, long term detection and logging of all measured values, even in network mode, the DL200D is the perfect measured data collector and an essential accessory for all precision measurements. Especially for calibration and testing laboratories.

A few practical benefits oft the DL200D:

  • 100% Trotec maintenance-free quality measuring device “made in Germany”.
  • Tamper-proof measured value detection and documentation
  • Optimal for long-term measurements
  • Simultaneous recording of up to 20 separate measuring channels
  • Network function (LAN)
  • Low energy consumption
  • Flexible power supply via battery or USB – or optionally with PoE, also via LAN
  • Timer function, variable measuring intervals, alarm function for each measuring channel
  • Three-row LCD for displaying measured values
  • Professional software included
