Thermometer (old & new)

It was often a troublesome thing to measure the body 

temperature of children. It took 10~15 minutes in old one.  

Thanks to the advance of microelectronics.  Now it take 

few minutes.

This is a Ear thermometer(OMRON). To measure the 

body temperature, just inserting the ear canal.  

This device can measure the temperature of tympanic 

membrane, using the refraction of infra-red beam.  

But not for suitable in child, since the ear canal of children 

is narrow and often difficult in infants.
