Homebrew PCBs

I measured the roller temperature as 287 degrees Fahrenheit (142 
degrees Celsius).  This  measurement was rather tricky to make.  I 
fed the thermocouple into the H200 laminator and attempted to turn it 
off just as the thermocouple junction entered the rollers.  Can't 
actually see to verify the thermocouple is properly placed so 
measurement may be low.  Repeated measurement several times and 
always found temperatures to be in the high 270s or low 280s ranges.

According to a prior post, the temperature should have been 361 F 
(183 C).  There is a large discrepancy here.  I might repeat the 
measurement tomorrow using a different thermocouple.  Perhaps someone 
can suggest a better measurement technique.
