There are three types of Thermocouple connector types: Mini Plug, Screw Terminal, and Terminal Block. Many of our thermocouple data loggers have different models available for each type of thermocouple connector. The first is a Mini Plug, and is the easiest connect as the thermocouple will be prewired into a plug-in terminal for you.

The second is the Screw Terminal, which requires that the data logger case be opened and the thermocouple wires be connected inside the data logger so that they cannot be removed without opening the data logger.

The last is the Terminal Block connection type, which has a greenie connected to the data logger. The thermocouple wires are connected to the greenie plug so that it can be removed from the body of the data logger.
