about temperature readings on HB:

 

unconfirmed. the thermal sensor on the heater box side is the feedback probe for controlling the temp you set. The temp read ( on the LED display) is from the exit side probe. The air temp entering the roasting chamber would then be limited to the 250 deg c max. 

Remember this unit is reading air temp. Not bean temperature. 

The heater side sensor seems to be type k embedded in hex screw, whereas on exhaust side, seems to be type k with metal sheath
