Infrared clinical thermometer

摘要: PROBLEM TO BE SOLVED: To provide an infrared clinical thermometer capable of reducing the dispersion measurement time a body temperature. SOLUTION: This is provided with ray sensor 101, control means 31, first amplifier 33, second 34, changeover switch 35, integration circuit 36, comparator 37, temperature 107, reference resistor 38, 39, relay 41, display part 5 and buzzer 42. Then, detection TP (signals from sensor) signals shortened as environment low, that difference large, prolonged low.
