system 1.Micoprocessor based servo controlled temperature 2.Two modes: Manual and automatic 3.Set temperature and skin temperature display separately 4.Anti-explosion micro crystal quartz for radiation source 5.Self-testing function, various failure alarms by audible and visual 6.Transparent protector can be folded down, with two infusion seals 7.RS232 connectorIncubators and radiant warmers are used to maintain the body temperature of newborn infants. This is best done so that the energy expended for metabolic heat production is minimized. The heat output of these devices is usually regulated by servocontrol to keep the skin temperature constant at a site on the abdomen where a thermistor probe is attached.
