MR2041 Handy Logger

Handy logger MR2041 is a palm size data logger, it capable to store up to 10000 data per each channel. Power supply of logger is selectable from AA battery or AC adaptor, so it is usable as a portable type logger or fixing type logger.

Using the exclusive software, recording/recalling of data and programming of logging parameters can be executed with logger or through a personal computer.


  • Input signals: K, E, J, T, 0 to 5V and 0 to 20mA;
  • Simultaneous 4 channels, measurement and display.
  • High/low alarms for each channel.
  • Computation: maximum / minimum / average.
  • Logging method: log mode and tag mode.
  • Data processable through a personal computer.
  • IP64 protection.
  • AA batteries power supply.
