As can be seen above, we are now able to track the temperature inside the reactor. To insert the thermocouple into the reactor, we used another lid for the reactor that had two connections. We sealed one of the connections that reaches into the reactor. This way, we can track the temperatures and different heights by just sliding the thermocouple in and out from the outside.
As we did not want to spend much money for an expensive temperature logger, we ordered only a K-type thermocouple and are using an Arduino MAX31855 chip and the Arduino library with the same name to convert the voltage output from the thermocouple to a temperature readout.
