How Is Glass Temp Measured? A pyrometer or thermal imager with a detector that is sensitive at 1 μm can be used to look through thin glass and measure wall temperatures as the glass emissivity is small and transmission is large. If there is sufficient glass thickness such as in the melt tank, then the
Can Alcohol Be Used In A Thermometer? alcohol is not used in thermometer. Mercury is used in it. Why do we use alcohol in thermometer? Alcohol thermometers are used rather than mercury thermometers in very cold regions because alcohol has a lower freezing point than mercury. Pure ethanol freezes at -115 degrees C, while mercury
What Is Fixed Point Of A Thermometer? We define two fixed points in thermometer. One is the freezing point (t0) and boiling point (t100). What are the fixed points of a liquid in glass thermometer? The lower fixed point is taken as 0 and the upper fixed point is taken as 100 . You can
