The ACK Long Life thermocouple with 9mm lock nut is 900mm in length and can provide temperature measurements over wide range of temperatures on wok cookers.
This is a genuine spare part which is made up of two wires of different metals that, when joined together, create an electrical junction. When the temperature changes at this junction it creates a voltage which can be interpreted to read the temperature by a thermometer connected at one end.
M Michelson –
Needed these quickly and they arrived next day. thanks.
Olivier Goddard –
Needed the 900 ones because 300mm were never long enough.
