Our temperature probes use RTD (resistive thermal device) Pt100 sensors instead of K-type thermocouples (TC) as they offer greater accuracy over the brewing temperature range. RTDs also remain more accurate over time (less drift which means less re-calibration).
Are temperature probe tips interchangeable?
Yes. Any of our temperature probe tips can be used with any of our temperature probe cables.
Why use a thermowell?
Some kettles come with thermowells (usually 1/2" NPT or Tri-Clover). Thermowells help protect the probe from damage during cleaning or from overzealous brewers with mash paddles where the probe is buried in grist and can't be seen.
Simply screw the temperature probe tip into the thermowell and then connect the cable. To ensure the fastest heat transfer reaction time, use the included heat sink grease between the probe tip and the thermowell wall.
