19世紀末與20世紀的紅外線耳溫計

2007-03-13 9:38 am
據我所知紅外線耳溫計早係1984已經面世,當時還未普及,到了2003年,才被廣泛使用,但請兩者之間有無沒有分別呢?
如果有,分別係咩呢?

Ear Thermometer
Pioneering biodynamicist and flight surgeon with the Luftwaffe during World War II, Theodore Hannes Benzinger invented the ear thermometer. David Phillips invented the infra-red ear thermometer in 1984. Dr. Jacob Fraden, CEO of Advanced Monitors Corporation, invented the world's best-selling ear thermometer, the Thermoscan® Human Ear Thermometer.

我想以前的耳溫計體型較龐大,量度時間比較快.

現在的耳溫計龐型很少,量度時間只需數秒,而且很精確,價錢亦很便宜.

沒有分別, 原理是一樣, 都是探測人體所發出的熱量
