Data Loggers Measurement Type - Temperature & Humidity


Estimated delivery within 4-7 working days

Measure and record up to four channels in One logger.

By coupling four units together, it is possible to simultaneously record up to 16 channels. This multi-channel battery powered data logger has an SD memory card slot with auto transfer capabilities to ensure your data is not lost when internal memory becomes full. It also comes with a touch panel for easy operation.

*1: When “Auto” is selected, measurement range will be automatically changed according to the voltage being measured.

*2: MCR-4TC has superior noise filter, but the measurement may sometimes fluctuate due to strong noise. Especially when the recording interval is set to 200 ms or less, the filtering becomes weaker and hence the fluctuation may become greater.

*3: If the logging capacity is not filled at the end of one recording session, the logger can record up to 30 times.

*4: Group Recording may not be started depending on the recording or measurement interval specifications of the connected Master unit.

*5: Please check the T&D Website for information on memory cards whose operation has been confirmed.

*6: Battery life varies depending upon multiple factors including ambient temperature, recording interval, number of measurement channels, and frequency of data export to a memory card. All estimates are based on operations carried out with a new battery and are in no way a guarantee of actual battery life.

*7: For installation, it is necessary to have Administrator (Computer Administrator) rights.

*8: We recommend using an operating system in the same language as the display language. Operation in different languages is not guaranteed.

*9: During the installation process of the software, if not present, .NET Framework 4 Client Profile will be installed automatically.

The specifications listed above are subject to change without notice.

  • For K, J, T, S and R Type Thermocouple Sensors - This 4-channel thermocouple temperature data logger brings you a wide range of measurement and is compatible with a wide variety of thermocouple sensors.
  • Easy Setup and Installation It is possible to remove the cover from the sensor and connect directly to the logger terminals. And because each channel as well as the USB is isolated it is okay to install without worrying about covering the point of measurement.
  • Logging Capacity of 960,000 Data Readings One logger can hold up to 960,000 readings using just 1 channel, up to 240,000 readings per channel using 4 channels.
