75 degrees = 68 degrees. No wonder I couldn’t get things to adhere well sometimes.
As a side note, the temp varies wildly along the plate base. An enclosure would definitely help here.
Has anyone else tested the actual temps versus the set/displayed temps and noticed a difference?
@eggspresso most infrared (IR) thermometers have a way to adjust the emissivity. Emissivity is basically how well the object gives off IR. As you suggested black electrical insulating tape is good. If it it thin tape then put two layers down. The emissivity of this is 95% which can be input into the thermometer.
