Thermocouple Sensors (for TR-75wb/75nw)
We do not handle the sale of Thermocouple sensors. Please purchase separately.
External Power Supply
It is possible to use USB bus power, AC adaptor (AD-05A2 or AD-05C2: sold separately), or PoE ( only) as a power source. When using an external power supply, installing batteries will make it possible to continue recording in the event of a power outage.
Important Notice for Using an External Power Supply
When using external power, the data logger itself generates heat and the internal sensor of the TR-71wb/71nw will report a higher temperature than actual; we recommend using an external temperature sensor. Also, when an external sensor is used near the TR-7wb/nw Series, it may be affected by the heat from the logger.
