We’ve added a port for a catalytic temperature probe just above the
center of the loading door. The probes are simple bimetallic coils
attached to a stainless rod. We have been testing the bimetallic probe
against a thermocouple: it’s certainly “in the ballpark” and gives a
good idea of catalyst light-off.
