The MESSKO combi well, like the thermo well, is an assembly sleeve for the oil thermometer. It can be installed in the thermometer pocket in accordance with DIN 42554. However, it also has an integrated Pt100 measuring resistor in accordance with DIN 43760 so that the measured temperature value can be transmitted remotely. The combi well consists of the immersion pipe and connection head.

The terminal connections for the evaluation devices (e.g. digital display) as well as a bushing for the immersion pipe for the temperature sensor of the pointer thermometer are located in the connection head.
