Abstract
Disclosed is an exhalation gaseous component gauge including, in a palm-sized casing having exhalation taking-in and taking-out slots made on its front and rear sides, a semiconductor gas sensor so placed that the air flowing from one's mouth may pass the sensor, a CPU responsive to the signal from the sensor for determining the quantity of the exhalation gaseous components, and a display for showing the so determined result. The palm-sized casing is so sized and configured as to permit one to have a look at the display while holding the gauge in hand to direct the air from the mouth to the exhalation taking-in slot. Also, disclosed is a cellular phone equipped with an exhalation gaseous component gauge.
