My sensor (I think a AD22100) only goes to 150C (302F) and provides the input voltage to an AVR ATmega168 chip - sorta limits how high the temperature can be controlled.
How many times thru depends on speed of rollers as well as temperature. Since this is a cheap $25 laminator I sorta hated to ask a LOT of temperature from it.
Next PCB I'll try up around 280F and see how that works. Seems like the laminator high temp thermal switch cuts off around 270F or so as measured at the roller input.
I am sure this is the same laminator sold by Pulsar.
