Pyrometers

[saltracer552@juno.com]

Does a scanning pyrometer exist? I would appreciate the capability of having 
real time EGT information during a run. Why scan? Since I can barely read the 
mile markers when I pass them having a multi-line display of appropriate size 
for my eyes would fill up the windshield. Hence a one line display with 3/4" or 
so digits. Clock to the next cylinder 1-2 second rate. Any thoughts?
