Description
The MCR-4TC Multichannel Temperature Recorder is designed to measure a wide range of temperatures using a thermocouple sensor. Up to four MCR loggers can be coupled together to allow for a maximum of 16 channels. After it measures and records temperature, the data can be easily displayed in graph form, enabling the immediate on-the-spot checking of continually-changing data.
When the bodies of multiple units are connected, the MCR-4TC at the far left side will be automatically designated as the Master
and all other connected MCR-4TC units will be designated as Slaves. By starting recording on the Master unit, all connected Slave units will start recording at the same time.
