HTF

nnnn

For continuously high temperatures ranging up to 1100°C a type

nnnn

'K' thermocouple should be used or a type 'N' if temperatures are

nnnn

likely to peak at 1300°C. If using a bare wire thermocouple then the

nnnn

element needs to be supported within ceramic insulators, but this is

nnnn

not necessary if the thermocouple being used is a mineral insu-

nnnn

lated (Ml) type.
