MR5300 Splash Proof Type Temperature Card Logger

MR5300 is a card size temperature logger, which can store max. 6,000 data. It has built-in temperature sensor, yet various external sensors are also available. The logger is dust tight and splash proof type washable, so dirt and stains can be washed away. Data can be read and set from PC.

  • IP64, dust tight and splash proof structure, so it is washable.
  • Conform to the CE marking
  • ±0.5°C (between -5to 50°C) of high accuracy
  • Compact, lightweight and easy operation
  • Acquired data can be stored for a long time on dead battery.
  • Stored data can be checked on the logger during data logging.
  • Measurement interval is 10 to 50sec. or 1 to 60min. available to set freely.
